Solve x squared - 14x equals -49?

Answer 1

63

Answer 2

x^2 - 14x = -49

x^2 - 14x + 49 =0, bring 49 to the other side by using addition

(x - 7) (x - 7) = 0 , factor the equation

x - 7= 0 , x - 7 = 0 , set everything equal to zero

x = 7

there is no need to put another x = 7 for the answer since both are the same.
