Question

Solve the equation x2 = 10.
A. x=±10−−√
B. x=10−−√
C. x=±5
D. x=5

Answer 1

ANSWER: D

EXPLANATION:
The x is being multiplied by 2 so you do inverse operations to get rid of it
So you divide the x by two and whatever you do on one side you have to do in the other so you divide the 10 by 2 giving you x=5

Answer 2

Answer:

A

Step-by-step explanation:

Given

x² = 10 ( take the square root of both sides )

x = ± $\sqrt{10}$
