Day 12 Homework - Solving Quadratics w/ Sq. Roots/Factoring

Solve by factoring:

2x²+ 7x + 6 = 0

• x= 3/2 and x = 2

• x = -3/2 and x = -2

• x = 6 and x = 7

• x = -6 and x = -7

Solve by factoring:

x² - 9x + 20 = 0

• x = -4 and x = -5

• x = 20 and x = -9

• x = 4 and x = 5

• x = -4 and x = 5

Solve by taking the square root:

5x² - 4 = 41

• x = 9 and x = -9

• x = 3 and x = -3

• x = 8 and x = -8

• No Real Number Solution

Solve by taking the square root:

(x + 2)² = 36

• x = -8 and x = 4

• x = -4 and x = 4

• x = -8 and x = 8

• x = - 38 and x = 34

Solve by taking the square root: 

(x - 3)² = 5

• x = 8 and x = -2

• x = 8 and x = -8

•  $x=3+\sqrt{5}\ \&\ \ x\ =\ 3-\sqrt{5}$ 

• x = 8
