Plsss answer, 35 pointss
write as a product of two polynomials.

1. x(y–5)–y(5–y)
2. (x–y)^2–a(y–x)
3. 2(3–b)+5(b–3)^2

1.

2.

3.

Step-by-step explanation:

1. The given polynomial is

We need to factor the second part to get:

We factor y-5 to obtain:

2. We have

We again factor -1 from the second part to get:

We now factor x-y to get:

3. We have

We factor negative 1 from the first part to get

We now factor b-3 to get:

We now simplify to get:

0

step-by-step explanation:

you can not divide by 0 so 4 ÷ 0 would be 0

0 × 9999 =0
