Question

Solve the equation graphically by converting it to an equivalent equation with 0 on the right-hand side and then finding the x-intercepts

Answer 1

\[2x-5=\sqrt{x+4}\]

Answer 2

Square both sides.

Answer 3

(2x-5)(2x-5)=x+4
4x^2-20x+25=x+4

Answer 4

subtract x+4 from both sides.

Answer 5

4x^2-21x+21

Answer 6

Now find the roots.

Answer 7

so would i factor?

Answer 8

Yeah, do it anyway you wish.
