Question

Solve the following equation for x. 7x^2 - 112 = 0

Answer 1

Answer:

x = 4, -4

is the answer

Answer 2

Answer:

x=4

hope it helps!

Step-by-step explanation:

7x^2 -112 = 0

7x^2 = 0+112

(When we bring -112 to the other side, it becomes positive)

So, 7x^2 = 112

x^2 = 112/7

x^2 = 16

Now since x squared is 16 it means that x into x is 16

Therefore, x= √16

and x= 4
