It is x = -5
x3 + 125 Use the sum of two cubes. (x+5)(x2-5x+25)
x3 + 4x2 + 6x + 24 = (x2 + 6)(x + 4)
x2 + 5x + 25
The answer to x4+x3-14x2+4x+6 divided by x-3 is x3+4x2-2x-2

5
No.
2x3 - 7 + 5x - x3 + 3x - x3 = 8x - 7
Anything plus 0 is itself, so x3 + 0 is x3.
x3 + x2 + 4x + 4 = (x2 + 4)(x + 1)
x3 + 4x2 + x + 4 = (x + 4)(x2 + 1)
x3 + 4x2 + 6x + 24 = (x2 + 6)(x + 4)
125 + 125 + 125 + 125 + 125 + 125 =125 * 6 =(100 * 6) + (20 * 6) + (5 * 6) =600 + 120 + 30 =600 + 100 + 20 + 30 =700 + 50 =750
x2 + 5x + 25
The answer to x4+x3-14x2+4x+6 divided by x-3 is x3+4x2-2x-2
