Question

Solve: s = 4 + √ s + 2 a. s=2 b. s=7 c. s=2 or s=7 d. no real solution

Answer 1

Answer:

on edgu its b. I just did XD

Step-by-step explanation:

Answer 2

Rewrite s = 4 + sqrt(s+2) as s-4 = sqrt(s+2)

Square both sides: s^2 - 8s + 16 = s + 2

combine like terms: s^2 - 9s + 14 = 0

Factor this: (s-7)(s-2)=0

Solve for s: s={7, 2}
