Find the product:
(2x+3)²

• 2x+3+2x+3
• 4x²+12x+9
• 4x²+9
• 16x²+9

Solve by factoring

3x²+19x+6=0

Solve by taking the root

4m² + 10 = 38

• m = 7, -7

• m = 7

• m = √7

• m = √7, -√7

Solve for x by taking the Square Root:

(x+6)² = 49

• x = 7 and 12

• x = ±7

• x = 1 and -13

• x = 43 and -55
