Question

Which equation can be rewritten as x + 4 = x^2? Assume x > 0

Answer 1

The answer is c, since this is the square root of both sides.

Answer 2

`√(x+4) =x`

Explanation:

`x+4=x^2`

Rewrite the given equation

To rewrite the given equation ,we need to remove the square from x on the right hand side.

To remove square we take square root onboth sides

`x+4=x^2`

Take square root on both sides

`√(x+4) =√(x^2)`

Square and square root gets cancelled

`√(x+4) =x`
