For all the questions, we will be using the FOIL pattern.
1. (x+3)(x-3)(3x+2)
(x^2-3x+3x-9)(3x+2)
(x^2-9)(3x+2)
3x^3+2x^2-27x-18
2. (2x+1)(x-2)(x+3)
(2x^2-4x+x-2)(x+3)
(2x^2-3x-2)(x+3)
2x^3+3x^2-11x-6
3. (x-3)(2x+1)(3x-2)
(2x^2+x-6x-3)(3x-2)
(2x^2-5x-3)(3x-2)
6x^3-19x^2+x+6
Hope this helped!

I'm going to simp. them one by one
- <span>(x+3)(x-3)(3x+2)
- (x</span>²-9)(3x+2)
<span>- (x</span>³+2x²-27x-18)
<span>-x</span>³-2x²+27x+18
<span>
- (2x+1)(x-2)(x+3)
- (2x</span>²-4x+x-2)(x+3)
<span>- (2x</span>²-3x-2)(x+3)
<span>-  [x(2x</span>²-3x-2)+3(2x²-3x-2)]
<span>- (2x</span>³-3x²-2x)+(6x²-9x-6)
<span>- (2x</span>³+3x²-11x-6)    (combined like terms)
<span>-2x</span>³-3x²+11x+6<span>

- (x-3)(2x+1)(3x-2)
- (2x</span>²+x-6x-3)(3x-2)
- (2x²-5x-3)(3x-2)
- [3x(2x²-5x-3)-2(2x²-5x-3)]
- (6x³-15x²-9x)+(4x²+10x+6)
- (6x³-11x²+x+6)
-6x³+11x²-x-6

All you need w/ these problems is a bit of patience and to know the foil-ing process and distribution. :D

Multiply the sum of -13/8 and 5/12 by their difference.​
REY [17]

Answer:

1421/576

Step-by-step explanation:

Sum = - 13/8 + 5/12 = - 39/24 + 10/24 = - 29/24

Difference = - 13/8 - 5/12 = - 39/24 - 10/24 = - 49/24

Sum * Difference = (-29/24)*(-49/24) = 1421/576
