Answer:
Recall that a quadratic equation is in standard form if it is equal to 0:
where a, b, and c are real numbers and . A solution to such an equation is called a root. Quadratic equations can have two real solutions, one real solution, or no real solution. If the quadratic expression on the left factors, then we can solve it by factoring. A review of the steps used to solve by factoring follow:
Step 1: Express the quadratic equation in standard form.
Step 2: Factor the quadratic expression.
Step 3: Apply the zero-product property and set each variable factor equal to 0.
Step 4: Solve the resulting linear equations.
For example, we can solve by factoring as follows:
