8x2 + 15 + 26x = 8x2 + 26x + 15 = 8x2 + 20x + 6x + 15 = 4x(2x + 5) + 3(2x + 5) = (2x + 5)(4x + 3)
x3 + 6x2 - 4x - 24 = (x + 6)(x2 - 4) = (x + 6)(x + 2)(x - 2)
8x+30=4x+18 -4x -4x 4x+30=18 -30 -30 4x=-12 4x/4=-12/4 x=-3
x2 + 4x + 3 = (x + 1)(x + 3)
3x-3x+4x^2+8x=4x^2+8x
5(4x + 9)
4x + 3 doesn't factor. It is in its simplest form.
4x(10x + 1)
It is: 4x(1+4)
(4x + 3)(4x + 3) (4x + 3)2
4x + 16 + 1 = 4x + 17 which cannot be factorised.
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
4x(4x^2 + 3x + 1)
(4x + 5)(4x + 5)
4x =20x=20/4x=5
No
4(x^2 + x + 3)
