Multiply: (x+a)^2-(x-b)^2+x^2+(a-b)x-ab by (a+b)

Step-by-step explanation:

Step-by-step explanation:the answer is =−a2b2y−ab3y+a2+3ax−b2+bx+x2    how did i get Distribute:

=a2+2ax+x2+−b2+2bx+−x2+x2+(a)(x)+(−b)(x)+−a2b2y+−ab3y

=a2+2ax+x2+−b2+2bx+−x2+x2+ax+−bx+−a2b2y+−ab3y

Combine Like Terms:

=a2+2ax+x2+−b2+2bx+−x2+x2+ax+−bx+−a2b2y+−ab3y

=(−a2b2y)+(−ab3y)+(a2)+(2ax+ax)+(−b2)+(2bx+−bx)+(x2+−x2+x2)

=−a2b2y+−ab3y+a2+3ax+−b2+bx+x2

hopes this help I just when back to my answer on my work and I had got a 100 last year.
