Question

Which statement describes how to solve √(3x+4)=√3x+4?

Answer 1

Answer:

C.) Square both sides twice and then solve the resulting linear equation.

Step-by-step explanation:

We are given a equation:

  $\sqrt{3x+4}=\sqrt{3x}+4$

On squaring both sides, we get

  $3x+4=3x+16+8\sqrt{3x}$

=  $8\sqrt{3x}=-12$

again on squaring, we get

  $64\times 3x=144$

⇒   x=3\4

Hence, solving this equation required Squaring both sides twice and then solving the linear equation

Hence, Correct option is:

C.) Square both sides twice and then solve the resulting linear equation.
