Answer 1

Hola (｡•̀ᴗ-)✧

a) x²=36

x = ±√36

x = ±6

b) a²=12

a = ±√12

a = ±2√3

c) x² - 8=28

x² = 28+8

x² = 36

x = ±√36

x = ±6

d) n² = 144

n = ±√144

n = ±12

e) -6m²=150

m² = 150/-6

m² = -25

m = ±√(-25)

m = ±√25 i

m = ±5i

f) m²+7=88

m² = 88-7

m² = 81

m = ±√81

m = ±9

g) n² -5= -4

n² = -4+5

n² = 1

n = ±√1

n = ±1

h) 8b²-7=193

8b² = 193+7

8b² = 200

b² = 200/8

b² = 25

b = ±√25

b = ±5
