# Quadratic equation solve by factoring

Solving Quadratic Equations by Factoring. From the example above, the quadratic problem simply reduces to a linear problem which can be solved by simple factorization. Example 1: Given x ^2+ 5x+ 6=0 \left(x+ 3\right)\left(x+ 2\right)=0 (factoring the polynomial) \left(x+ 3\right)=0 OR \left(x+ 2\right)=0. Thus x=-3, Or x=-2.

Students learn that the first step to solving polynomial equations is to set the given equation equal to zero; the next step is to factor; and the final step is to set each of the resulting factors equal to zero and solve each equation, which yields more than one solution, so the answer can be written as a solution set. Solve Quadratic Equations by Factoring. This bunch of pdf exercises for high school students has some prolific practice in solving quadratic equations by factoring. Factor and solve for the real or complex roots of quadratic equations with integer, fractional, and radical coefficients. Solve Quadratic Equations by Taking Square Roots The second method, factoring, becomes much more difficult as the quadratic equation becomes more complex. For example, it is much easier to factor a quadratic equation in the form ax 2 + bx + c where a = 1 than it is to factor a quadratic equation in the form ax 2 + bx + c where a ≠ 1. Solving Quadratic Equations: The Quadratic Formula This page will try to solve a quadratic equation by factoring it first. How does this work? Well, suppose you have a quadratic equation that can be factored, like x 2 +5x+6=0. This can be factored into (x+2)(x+3)=0. So the solutions must be x=-2 and x=-3. Note that if your quadratic equation cannot be factored, then this method will not work. Students learn that the first step to solving polynomial equations is to set the given equation equal to zero; the next step is to factor; and the final step is to set each of the resulting factors equal to zero and solve each equation, which yields more than one solution, so the answer can be written as a solution set. A quadratic equation is any second degree polynomial equation — that’s when the highest power of x, or whatever other variable is used, is 2. You can solve quadratic equations by factoring. Bring all terms to one side of the equation, leaving a zero on the other side. Factor. (2x + 3)(x – 4) = […] Steps Now we can solve Quadratic Equations in 5 steps: Step 1 Divide all terms by a (the coefficient of Step 2 Move the number term (c/a) to the right side of the equation. Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation. Objective: Solve quadratic equation by factoring and using the zero product rule. When solving linear equations such as 2x − 5 = 21 we can solve for the variable directly by adding 5 and dividing by 2 to get 13. However, when we have x2 (or a higher power of x) we cannot just isolate the variable as we did with the linear equations. • Solve a quadratic equation by factoring a GCF. • Solve a quadratic equation by factoring when a is not 1. • Create a quadratic equation given a graph or the zeros of a function.

Mar 27, 2015 · No, it depends on the sign of the discriminant. If the discriminant is negative, the quadratic has no solution (at least, no real solutions), and so it cannot be further simplified. If the discriminant is zero, it means that the polynomial has a zero x_0 with molteplicity two, and this means that p(x)=(x-x_0)^2. You can fully solve the equation (and by this I mean writing p(x)=(x-x_1)(x-x_2 ... Unfortunately, you won't be able to solve every quadratic equation with this method. If you end up with a quadratic expression that can't be factored, you'll need to solve it a different way. If this happens, you can solve it by using a method called completing the square, or by using the quadratic formula.
