if it is to the 2nd power it is 64 if it is to the 3rd power it is 512 .
2 to the 3rd power = 8
2 to the 3rd power = 2 * 2 * 2 = 8
23 = 8
20x2 - 27x -8 20 * -8 is -160, and -32 and 5 add to -27 20x2 - 32x + 5x - 8 4x(5x-8) + 1(5x-8) (4x + 1)(5x-8)
the answer is (3x-2)(9x squared+6x+4)

I also need to know the answer to this problem. Can anyone answer it?
27X^3-8 = 0 27X^3 = 8 X^3 = 8/27 X = cubic root of 8/cubic root of 27 = 2/3
(2x - 5)(4x^2 + 10x + 25)
The prime factorization of 8 is 2^3. The prime factorization of 27 is 9 x 3.

2 to the 3rd power.
To factor: 10x2 + 27x - 28 Find two values that add up to 27, our middle coefficient, and which multiply to make -280, the product of the other two coefficients. In this case, those two values would be 35 and -8. Now break the middle term down with those two values, and factor: = 10x2 + 35x - 8x - 28 = 5x(2x + 7) - 4(2x + 7) = (5x - 4)(2x + 7)
if it is to the 2nd power it is 64 if it is to the 3rd power it is 512 .
