Question

What is the solution to x=sqrt(2x+3)

Answer 1

Square both sides to get rid of the square root.

Answer 2

so let me see if im getting what your saying... so square 2x and 3 right

Answer 3

you have: \(\sf x^2=2x+3\). Which looks like....a polynomial that you can factor.

Answer 4

Remember that \(\sf \sqrt{x} = x^\frac{1}{2}\), so when you square it, you have: \(\sf [x^\frac{1}{2}]^2\) Which is basically \(\sf x^1=x\)
