X\Xb2=16, T\Xb2=81, R\Xb2-100=0, X\Xb2-144=0, 2s\Xb2=50, Paki Sagot Po Quadratic Equation By Extracting Square Roots..

X²=16

t²=81
r²-100=0
x²-144=0
2s²=50
Paki sagot po quadratic equation by extracting square roots..

Step-by-step explanation:

  • x²=16

x=±√16

x=±4

x=4 or x=-4

  • t²=81

t=±√81

t=±9

t=9 or t=-9

  • r²-100=0

r²=100

r=±√100

r=±10

r=10 or r= -10

  • x²-144=0

x²=144

x=±√144

x=±12

x=12 or x= -12

  • 2s²=50

/2 both sides of the equation

s²=25

s=±√25

s=±5

s=5 or s= -5
