Quadratic Solve Square Root

• No real solutions

Solve by taking square roots:
a² + 9 = 9

• no solution

• a = 0

• a = 3 or -3

• a = 18

Solve by taking square roots:
5b² - 4 = 41

• b = 9, b = -9

• b = 3, b = -3

• b = 8, b = -8

• no solutionb

Solve for x.
-9p² = -576

• x = 8

• x = 64

• x = 8, -8

• x = 64, -64

When solving a quadratic equation, when do you use the plus or minus (±) symbol?

• After taking the square root of both sides

• After adding the square to both sides

• After taking half of b

• After setting the equation equal to zero
