Answer:

Prime:  x^2 + 17x - 30.

Difference of 2 squares:  256x^4 - 49x^2.

GCF:  4x^2 - 24x + 144.

Perfect Square trinomial:  4a^6 - 28a^3 + 49

Factoring Trinomial: b^2 + 5b - 36.

Step-by-step explanation:

1.  x^2 + 17x - 30 will not factor.

2.  256x^4 - 49x^2 = (16x^2 + 7x)(16x^2 - 7x)

3.   4x^2 - 24x + 144 = 4(x^2 - 6x + 36).

4.   4a^6 - 28a^3 + 49 = (2a^3 - 7)^2.

5.    b^2 + 5b - 36 = (b + 9)(b - 4).

V = lwh

V = (x + 2)(x + 3)(x)

V = (x)(x^2 + 3x + 2x + 6)

V = (x^3 + 3x^2 + 2x^2 + 6x)

V = x^3 + 5x^2 + 6x

All you do is foil the dimensions together and then combine like terms. Hope this helps!
