Question

Which equation results from isolating a radical term and squaring both sides of the equation for the equation

Answer 1

Answer:

$c - 2 = 25 + 10 \sqrt c + c$

Step-by-step explanation:

Given

$\sqrt{c-2} - \sqrt c = 5$

Required

Isolate radical, then square both sides

We have:

$\sqrt{c-2} - \sqrt c = 5$

Isolate radical

$\sqrt{c - 2} = 5 + \sqrt c$

Square both sides

$(\sqrt{c - 2})^2 = (5 + \sqrt c)^2$

$c - 2 = 25 + 2 * 5 * \sqrt c + c$

$c - 2 = 25 + 10 \sqrt c + c$
