Quizplus · Accepted Answer

The square root property is directly used when an equation is in the form $x^2 = a$ or $(\text{expression})^2 = a$, where $a$ is a constant. Option D, $(4x + 7)^2 = 8$, is already in this form, allowing for the direct application of the square root property.

Solve the Problem 4x2+7x−8=04 x ^ { 2 } + 7 x - 8 = 04x2+7x−8=0
