is this quadratic equation

This is solution for the third image

x^2 + 2x - 24

x^2 + 6x - 4x - 24

x (x + 6) - 4 (x + 6)

(x + 6) (x - 4)

x + 6 = 0    ,    x - 4 = 0

Therefore, x = - 6  ,  x = 4

This solution is for the first image

2x^2 + 14x + 24

2x^2 + 8x + 6x + 24

2x (x + 4) + 6 (x + 4)

(x + 4) (2x + 6)

x + 4 = 0    ,    2x + 6 = 0

Therefore, x = - 4   ,   2x = 6

                                   x = 6/2 = 3
