2. Solving Equations by Taking the Square Root on Both Sides
★It’s important to note that we can only solve by taking the square root on both side, when the quadratic has no linear term (no b value).
Solve:
variable
𝑏 = 0
1. Get the 𝑥 2 by itself
2. Square root both sides and
write ± for each root
3. Simplify the radical
