pls help , send full answer with complete explanation ​

Answer 1

Answer:

−14x2+xy+32

Step-by-step explanation:

Let's simplify step-by-step.

6x2+9xy−11+3x2+4xy+14

=6x2+9xy+−11+3x2+4xy+14

Combine Like Terms:

=6x2+9xy+−11+3x2+4xy+14

=(6x2+3x2)+(9xy+4xy)+(−11+14)

=9x2+13xy+3

Let's simplify step-by-step.

3x2−7xy+21+8−8x2−5xy

=3x2+−7xy+21+8+−8x2+−5xy

Combine Like Terms:

=3x2+−7xy+21+8+−8x2+−5xy

=(3x2+−8x2)+(−7xy+−5xy)+(21+8)

=−5x2−12xy+29

Let's simplify step-by-step.

−5x2−12xy+29−9x2+13xy+3

=−5x2+−12xy+29+−9x2+13xy+3

Combine Like Terms:

=−5x2+−12xy+29+−9x2+13xy+3

=(−5x2+−9x2)+(−12xy+13xy)+(29+3)

=−14x2+xy+32
