Answer:
=x^2+5x+2+−1(5x^2−x−2)
=x^2+5x+2+−1(5x^2)+−1(−x)+(−1)(−2)
=x^2+5x+2+−5x^2+x+2
=x^2+5x+2+−5x^2+x+2
=(x^2+−5x^2)+(5x+x)+(2+2)
=−4x^2+6x+4
Answer:
-4x^2 +6x+4
Step-by-step explanation:
(x^2 +5x+2) - (5x^2-x-2)
Distribute the minus sign
(x^2 +5x+2) - 5x^2+x+2
I like to line them up vertically
x^2 +5x+2
- 5x^2+x+2
