*Solving Quadratic Equations by extracting square roots (With solution pls.)

1. 2s=16
2. -5x=35
3. 3h-2=16
4. -7x=-28
5. 3(x+7)=24
6. 2(3k-1)=28

1) 2s = 16
s = 16/2 = 8

2) -5x = 35
x = 35/-5 = -7

3) 3h - 2 = 16
3h = 16+2
3h = 18
h = 18/3 = 6

4) -7x = -28
x = -28/-7 = 4

5) 3(x+7) = 24
x+7 = 24/3 = 8
x = 8-7 = 1

6) 2(3k-1) = 28
3k-1 = 28/2 = 14
3k = 14+1 = 15
k = 15/3 = 5
