x3+3x2+6x+1 divided by x+1 Quotient: x2+2x+4 Remaider: -3
4x(4x^2 + 3x + 1)
The 3x is cubed and the 4x is squared
9x2 + 3x / 3x equals (3x + 1).9x2 + 3x divided by x is 9x + 3 , and then divided by 3 yields the 3x +1.
Factorise it: (x + 5)(3x - 8)
x3+3x2+6x+1 divided by x+1 Quotient: x2+2x+4 Remaider: -3
3x3+15x2+18x = 3x(x2+5x+6) = 3x(x+2)(x+3)
4x(4x^2 + 3x + 1)
the answer is (3x-2)(9x squared+6x+4)
24
(x + 2)(3x - 1)(3x + 1)
The 3x is cubed and the 4x is squared
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
(8x + 9)(3x^2 - 1)
9x2 + 3x / 3x equals (3x + 1).9x2 + 3x divided by x is 9x + 3 , and then divided by 3 yields the 3x +1.
Factorise it: (x + 5)(3x - 8)
