Answer:
-4x+1
Step-by-step explanation:
Sum of 3x
2
−5x+2 and −5x
2
−8x+6
=(3x
2
−5+2)+(−5x
2
−8x+6)
Rearranging and collecting the like terms, we get:
=3x
2
−5x
2
−5x−8x+2+6
=(3−5)x
2
−(5−8)x+2+6
=−2x
2
−13x+8
Now Subtract 4x
2
−9x+7 from −2x
2
−13x+8
(−2x
2
−13x+8)−(4x
2
−9x+7)
=−2x
2
−13x+8−4x
2
+9x−7
=−2x
2
−13x+8−4x
2
−9x−7x
Rearranging and collecting the like terms, we get:
=−2x
2
−4x
2
−13x−9x+8−7
=(−2−4)x
2
−(13+9)x+8−7
=−6x
2
−4x+1
