Question

PLS PLS help me create a new polynomial identity ASAP!!!!!

(y+x) + (ax+b)

Square the expression on the left, then add the expression on the right.

Answer 1

ax + b + y^2 + 2yx + x^2

Explanation:

(y+x)^2

= (y+x)(y+x)

= y^2 + 2yx + x^2

y^2 + 2yx + x^2 + (ax+b)

= ax + b + y^2 + 2yx + x^2
