Question

Gente ok pra hoje

x²+3=124

2x²-2=12

X+3=2+1

2x+48=48

Answer 1

X²+3=124
X²=124-3
X²=121
X=±√121
X=11


2x²-2=12
2x²=12+2
2x²=14
X²=14/2
X²=7
X=±√7

X+3=2+1
X=3-3
X=0

2x+48=48
2x=48-48
2x=0
X=0/2
X=0



Espero ter ajudado :-)

Answer 2

a) x² + 3 = 124

x² = 124 - 3

x² = 121

x² =  √121

x = 11

S = {11 e - 11}

_______________________________

b) 2x² - 2 = 12

2x² = 12 + 2

2x² = 14

x² = 14/2

x² = 7

x² = √7

S = { √7 e - √7 }.

_______________________________.

c) x + 3 = 2 + 1

x = 3 - 3

x = 0

_______________________________

d) 2x + 48 = 48

2x = 48 - 48

2x = 0

x = 0
