Answer:
Explanation:
Solving by factoring is a strategy used to solve quadratic equations, which are polynomials of the form ax^2 + bx + c = 0. The goal of this strategy is to factor the quadratic expression on one side of the equation and set each factor equal to zero to find the solutions of the equation.For example, consider the equation x^2 - 6x + 8 = 0. To solve this equation by factoring, we can first find the factors of the constant term (8) which are 1 and 8. And the factors of the leading coefficient (1) and the constant term (8) which are (1,-8) and (1,8). We can then use the distributive property to rewrite the equation as (x - 4)(x - 2) = 0.Once we have factored the quadratic expression, we set each factor equal to zero and solve for x. In this case, x - 4 = 0 and x - 2 = 0. Solving for x, we get x = 4 and x = 2. These are the solutions to the equation.We can check our solutions by plugging them back into the original equation to see if they make the equation true.x = 4 and x = 2 are the solutions of the equation x^2 - 6x + 8 = 0.It's important to note that factoring can also be used to solve equations that are not in the standard form, like x^2 - 6x + 8 = 12 by subtracting 12 from both sides of the equation, and then factor the left side.In summary, factoring is a strategy used to solve quadratic equations by factoring the quadratic expression on one side of the equation, setting each factor equal to zero, and solving for x. The solutions of the equation are the values of x that make the equation true.
