Here you go:

$a\left(a\right)+a(-b)+(-b)a+(-b)(-b)=$

$={a}^{2}-ab-ba+{b}^{2}=$

$={a}^{2}-2ab+{b}^{2}$

You can use the FOIL method:

First multiply the first terms in (a-b)(a-b):

$a\left(a\right)={a}^{2}$

Add the products of the outside and inside terms:

${a}^{2}+a(-b)+a(-b)={a}^{2}-2ab$

Finally, add the product of the last terms:

$a}^{2}-2ab+(-b)(-b)={a}^{2}-2ab+{b}^{2$

First multiply the first terms in (a-b)(a-b):

Add the products of the outside and inside terms:

Finally, add the product of the last terms:

If the directions is to simplify the following polynomials, then explain what I perhaps did wrong or explain what the answer should be.

$3{x}^{2}\left(5x\right)(-\frac{2}{3}{x}^{3})\to 15{x}^{3}-2{x}^{5}$
