Answer 1

Explicación paso a paso:

1. (3x)(5x)=

=3*x*5*x

=15*x2

=15x^2

2. (2x)(-x) =

=−2x^2

3.(3x2)(-5x) =

=3*x2*(−5)*x

=−15*x3

=−15x^3

4. (-x)(-4x2)=

=4x^3

5. (-3x)(-x) =

=3x^2

6. (-8x)(5x)=

=(−8)*x*5*x

=−40*x2

=−40x^2

7. (7x)(3x3)=

=7*x*3*x3

=21*x4

=21x^4

8. (-5)(x2) =

=−5*x2

=−5*(x*x)

=−5x^2

9. (-4x2)(-3x)=

=(−4)*x2*(−3)*x

=12*x3

=12x^3

10. (-1)(-x2) =

=x^2

11. (-1)(2x3)=

=−2x^3

12. (-1)(x)=

=−1*x

=−x
