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.

it 2

step-by-step explanation:

8^1/3=2

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
