Question

Which equation can be rewritten as x + 4 = x2? Assume x greater-than 0 StartRoot x EndRoot + 2 = x StartRoot x + 2 EndRoot = x StartRoot x + 4 EndRoot = x StartRoot x squared + 16 EndRoot = x

Answer 1

We have been given an equation $x+4=x^2$. We are also told that x is greater than 0. We are asked to choose the equation that can be written as our given equation.

Since x is greater than, so we will take positive root on both sides of our given equation as:

$\sqrt{x+4}=\sqrt{x^2}$

$\sqrt{x+4}=x$

Upon looking at our given choices, we can see that option C is same as our answer.

Therefore, option C is the correct choice.
