Problem N 31

we have the expression

`(3x^2-6x-4)\cdot(5x+2)`

Apply distributive property

`3x^2(5x)+3x^2(2)-6x(5x)-6x(2)-4(5x)-4(2)`
`15x^3+6x^2-30x^2-12x-20x-8`

Combine like terms

`15x^3^{}-24x^2-32x-8`

therefore

The answer is option A

Problem N 35

we have

2x^3-9x^2+3x+4 : ( x^2+2x-1)

2x-13

-2x^3-4x^2+2x

----------------------

-13x^2+5x+4

13x^2+26x-13

--------------------

31x-9

Therefore

The answer is option A
