Solve each of the following quadratic equation by extracting square roots.label every step of your solution with the steps of solving by extracting square

Sagot :

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:
