Question

Determine as raizes das equaçãos
x^2=100
4×^2-100=0
4x^2-36=0
2x^2-2=96
3x^2-121=x^2+41​

Answer 1

X^2 = 100

x = 10

4x^2 - 100 = 0

x^2 = 100/4

x^2 = 25

X = 5

4x^2 - 36 = 0

x^2 = 9

x =3

2x^2 - 2 = 96

X^2 = 49

X = 7

3x^2 - 121 = x^2 +41

3x^2 - x^2 = 121 + 41

2x^2 = 162

x^2 = 81

x = 9
