Question

Solve the equation. If necessary, round your answer to the nearest tenth.

Answer 1

X^2 =196
x^2 -196=0
(x-14)*(x+14)=0
so (x-14)=0 && (x+14)=0
x=14 , -14
the answer is B

Answer 2

Answer:

14, -14

Step-by-step explanation:

x^2 = 196

x = $\sqrt{196}$

x = $\sqrt{4 * 49}$

x = $\sqrt{4}$ * $\sqrt{49}$

x = 2 * 7

x = 14
