X = 7W? + 4w - 6<br> Y =w2 - 11w +13<br> X-Y<br> Your answer should be a polynomial in standard fom.
svp [43]

Answer: w^2-22w+19

Step-by-step explanation:

X=7w+4w-6\\Y=w^2-11w+13\\

(7w+4w-6)-(w^2-11w+13)\\7w+4w-6-w^2+11w-13\\(7w+4w+11w)+(-6-13)-w^2\\22w-19-w^2\\-w^2+22w-19

Normally we wouldn't have our square variable be negative, so in order to get rid of that negative sign without changing the equation is by multiplying by -1

-1(-w^2+22w-19)\\=w^2-22w+19
