Question

Math help please!!!
**check picture below**

Answer 1

Simple...


`(3x y^(3) )(2 x^(3)y)`

3*2=6


`x* x^(3)= x^(4)` (Exponents "multiplied" are added)


`y^(3) *y= y^(4)`

Making it...


`6 x^(4)y ^(4)`

Thus, the answer to your first question.

The Second One....


`(x^(2) -2x-2)*( x^(2) +2x+3)`

It looks hard, but it's not...break it down..


`x^(2) * x^(2) = x^(4)`


`x^(2) *-2x=-2 x^(3)`


`x^(2) *2x=2 x^(3)`


`x^(2) *-2=-2 x^(2)`


`-2x*2x=-4 x^(2)`


`x^(2) *3=3 x^(2)`

-2*2x=-4x

-2x*3=-6x

-2*3=-6

Now..FINALLY...add it up..

Making the answer to your second equation...


`x^(4) -2 x^(3) +2x ^(3) -6x ^(2) +3 x^(2) -10x-6`


`x^(4) -3x ^(2)-10x-6.`
