Solve the following quadratic equations by extracting square roots. answer the questions that follow. 1. x²=16 2. t²=81 3. r²=100=0 4. x²-144=0 5. 2s²=50

1.  x=±4

2. t=±9

3. r=±10

4. x=±12

5. s=±5

Step-by-step explanation:

1. x^2 = 16

Taking square root on both sides

x=±4

2. t^2=81

Taking square root on both sides

t=±9

3. r^2-100=0

r=±10

4. x²-144=0

x²=144

Taking square root on both sides

x=±12

5. 2s²=50

s=±5 ..
