Find two consecutive even negative integer is such that the square of the first added to twice the second is 124 find the numbers

Answer 1

The first number would be negative 12 and the second is negative 10

Answer 2

x^2 + 2(x + 2) = 124

x^2 + 2x + 4 = 124

x^2 + 2x - 120 = 0

(x + 12)(x - 10) = 0

x + 12 = 0

x = -12

-12,-10
