Answer:
12y^2-7
Step-by-step explanation:
Let's simplify step-by-step.
2y2+5xy−8−(5xy−1−10y2)
Distribute the Negative Sign:
=2y2+5xy−8+−1(5xy−1−10y2)
=2y2+5xy+−8+−1(5xy)+(−1)(−1)+−1(−10y2)
=2y2+5xy+−8+−5xy+1+10y2
Combine Like Terms:
=2y2+5xy+−8+−5xy+1+10y2
=(5xy+−5xy)+(2y2+10y2)+(−8+1)
=12y2+−7
Answer:
=12y2−7
