Question

Write as a product of two polynomials: x(y–5)–y(5–y)

Answer 1

(y + x) (y - 5)

Explanation:

1. x (y - 5) -y ( 5 - y)

2. xy - 5x - 5y + y^2

3. (y + x) (y - 5)

Answer 2

`(x+y)(y-5)`

Explanation:

`x(y-5)-y(5-y)\\\\x(y-5)-y[-(y-5)]\\\\x(y-5)+y(y-5)\\\\Take\ (y-5)\ common\\\\(x+y)(y-5)`
