Please help solve this math problem.

Solve for u, where u is a real number. Squareroot -2u + 8 = u (If there is more than one solution, separate them with commas.) u =

solution:

(-2u+8) = u

squaring on both side we get

-2u +8 = u²

+2u -8 +u²=0

u² + 2u -8 =0

u²+4u-2u-8 =0

(u+4) (u-2) = 0

u = -4 and u= 2

Answer: u=2 , -4
