Question

From the sum of 3x? - 5x + 2 and - 5x? - 8x + 6 subs tract 4x2 - 9x + 7
​

Answer 1

Answer:

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−7

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
