Use a^3 + b^3 = (a + b)(a^2 - ab + b^2), where a^2 is a squared, a^3 is a cubed. Note that 216 = 6^3.
No
2(3x^2 + 6x + 2)
(3x+1)(x+2)
The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers or expressions. You have only one expression in the question! The greatest factor of any expression is itself.
2(8y + 1)
3(2 + y)
It is: 2(4x+5)
2(x+3)
(y + 8)(y - 2)
3(2y + 3)(y + 2)
x2 + 6x + 8 =(x + 2)(x +4)
(x - 2)(2x - 3)
the answer is (3x-2)(9x squared+6x+4)
You factor out 5 from the expression (10+5p). You get 2(5+p).
It is 7*(1 + 2).
It can't be factored because the discriminant of this quadratic expression is less than zero.
