Question

Solve the following quadratic equation
(X+12)^2=1

Answer 1

x = -11 and -13

Explanation:

expanding the equation

x²+24x+144 = 1

x²+24x+143=0

(x+a)(x+b) = 0, where ab = 143 and a+b = 24

11X13 = 243 11+13 = 24

(x+11)(x+13) = 0

x +11 = 0; x = -11

x+ 13 = 0, x = -13

Answer 2

-11 and -13
