Find the solution for the quadratic equation by completing the square.
x^2+18x=63

Good evening ,

Step-by-step explanation:

x²+18x=63 ⇌ x²+18x+81 = 63 + 81

⇌ (x+9)² = 144  ⇌ (x+9)² = 12² ⇌ (x+9-12)(x+9+12) = 0

⇌ (x-3)(x+21) = 0

⇌ x=3 or x=-21.

:)

the answer is B -21, 3

step-by-step explanation:
