solve the quadratic equation by extracting square roots. label every step of your solution with the steps og solving by extracting square roots x²=1/25
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 ≠ 0. 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:
Solve by extracting square roots:
Step 1: Begin by isolating the square. (Good thing, it's already isolated)
Step 2: Apply the square root property.
