x3+8y3 = (x+2y)(x2-2xy+4y2)
The discriminant of the quadratic factor is 4y2-16y2 < 0 so there are no real roots.
So the only real root of the original polynomial is x+2y=0 or x = -2y
2 cubed = 2*2*2 =8. 8+8+8= 24
105 squared plus 8 cubed is equal to 11,537.
The polynomial IS b2 - 6b + 8.
(x-3)(x+8)
The answer is 537

X3 + 8= (x+2)(x2-2x+4)
2 cubed = 8 8 cubed = 512
(2x + 5)(4x^2 - 10x + 25)
the answer is (3x-2)(9x squared+6x+4)
2 cubed = 8
To cube a number, just use it in a multiplication 3 times. Thus 8 x 8 x 8 = 5123 + 64 = 576
