Question
factoring quadratic equations
Solution
Sure, here are the steps to factor a quadratic equation:
-
Identify the quadratic equation: Quadratic equations are in the form ax^2 + bx + c = 0, where a, b, and c are constants.
-
Factor the equation: The goal is to rewrite the equation as (dx + e)(fx + g) = 0, where d, e, f, and g are also constants.
-
Set each factor equal to zero: This gives you two equations, dx + e = 0 and fx + g = 0.
-
Solve each equation: This will give you the solutions to the original quadratic equation.
Let's take an example:
Factor the quadratic equation x^2 + 5x + 6 = 0.
-
Identify the quadratic equation: Here, a = 1, b = 5, and c = 6.
-
Factor the equation: We need two numbers that multiply to 6 (c) and add to 5 (b). The numbers 2 and 3 fit this criteria, so we can rewrite the equation as (x + 2)(x + 3) = 0.
-
Set each factor equal to zero: This gives us the equations x + 2 = 0 and x + 3 = 0.
-
Solve each equation: Solving these gives us x = -2 and x = -3. These are the solutions to the original quadratic equation.
