the square root of the square of a # increased by 5 added to the # is equal to 5.find the number
sqrt(x^2 + x + 5) = 5
x^2 + x + 5 = 25
x^2 + x - 20 = 0
(x - 4) (x + 5) = 0
x = 4 or x = -5
CHECK:
sqrt(x^2 + x + 5) = 5
sqrt(4^2 + 4 + 5) = 5
sqrt(25) = 5
5 = 5 check good answer
sqrt(x^2 + x + 5) = 5
sqrt((-5)^2 - 5 + 5) = 5
sqrt(25) = 5
5 = 5 check good answer
(4, -5)
