Problem N 31
we have the expression
[tex](3x^2-6x-4)\cdot(5x+2)[/tex]Apply distributive property
[tex]3x^2(5x)+3x^2(2)-6x(5x)-6x(2)-4(5x)-4(2)[/tex][tex]15x^3+6x^2-30x^2-12x-20x-8[/tex]Combine like terms
[tex]15x^3^{}-24x^2-32x-8[/tex]therefore
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
