Question

What is the difference of the two polynomials?

(7y2 + 6xy) – (–2xy + 3)
A7y2 + 4xy – 3
B7y2 + 8xy – 3
C7y2 + 4xy + 3
D7y2 + 8xy + 3

Answer 1

B 7y2 + 8xy - 3 because 2xy becomes positive and 3 negative

Answer 2

`7y^2+8xy-3`

Step-by-step explanation:

The difference of polynomial means subtracting the two polynomials

We have been given two expressions
`7y^2+6xy` and
`-(-2xy+3)`

We need to subtract the given two polynomials

Given expression can be rewritten as

`7y^2+6xy+2xy-3`

After simplifying means solving like terms that is the term of same variable we will get

`7y^2+8xy-3`
