Question

Solve the equation.

x^2 + 18x + 81 = 25

Answer 1

Bring the 25 over to the left side, simplify. Try to factor the quadratic expression. If that is not possible use the quadratic formula to solve for x.

Answer 2

I think it's 14, -14

Answer 3

use quadratic formula for x^2+18x=-56

Answer 4

x^2 + 18x + 81 = 25
x^2 + 18x + 81 -25 = 0
x^2 + 18x + 56 = 0
x^2 + 4x + 14x + 56 = 0
x(x + 4) + 14(x + 4) = 0
(x + 4)(x + 14) = 0
x = -4 or x = -14.

Answer 5

but that gives you -187
