x^2 + x - 12 = 0
x^2 + 4x - 3x - 4*3 = 0
(x + 4)(x - 3) = 0
(x + 4)(x - 3) = 0 is in factored form.

The following points of (-3, 21) lies on the graph of y = x^2 - 2x + 6.
When x = -3
y = (-3)^2 - 2*(-3) + 6
y = 9 + 6 + 6
y = 9 + 12
y = 21

The equations of (x + 3)(x + 4) = 5 is quadratic.

If (x + 5)(x - 2) = 18, then the statements of x + 7 = 0 or x - 4 = 0 is true .
(x + 5)(x - 2) = 18
x^2 + 5x - 2x - 10 = 18
x^2 + 3x - 28 = 0
x^2 + 7x - 4x - 7*4 = 0
(x + 7)(x - 4) = 0
So x + 7 = 0 , or x - 4 = 0
