Answer:
11x^(2) - 3
Step-by-step explanation:
Remove the parentheses: (a)=a
=5x^2-7x+10+7x^2-11-x^2+7x-2
Group the like terms:
=5x^2+7x^2-x^2-7x+7x+10-11-2
Add the similar elements : 5x^2+7x^2-x^2=11x^2
=11x^2-7x+7x+10-11-2
Continue to add similar elements: -7x+7x=0
=11x^2+10-11-2
Then add or subtract the numbers: 10-11-2=-3
<u>FINAL ANSWER</u>:= <em>11x^(2)-3</em>
Answer:
