18 because, 5x2=10 10+8=18! Your welcome. It's not a problem at all. I love math!
If you notice, 8x + 4 = 4(2x + 1), but there is an odd coefficient for x2, so there is guaranteed to be some remainder (that is 8x + 4 is not a factor of the polynomial): (24x3 - 5x2 - 48x - 8) ÷ (8x + 4) = 3x2 - 2x - 5 - (x2 - 12)/(8x + 4)
It is 4x^2 + 10x - 1
5x2-8x-4
(x - 2)(x - 2)(x - 1)

(x - 2)(x - 2)(x - 1)
(8x - 21)(8x + 21)
5x2 + 3x + 8x2 = 13x2 + 3x = x(13x + 3)
2x3 - 7 + 5x - x3 + 3x - x3 = 8x - 7
That does not factor neatly.
-8x + 3x2 - 3
In algebra and mathematics the simple above equation can be written and simplified as follows . (5x2 8x)-(3x2-x) = 10 + 8x -6 +x = 4 +7x.
x2 + 8x + 15 = (x + 3)(x + 5)
