Subtract:
-x2+10x-5 from 5x - 10
On combining the like terms and subtracting them we get
= 5x – 10 – (-x2 + 10x – 5) = 5x – 10 + x2 – 10x + 5
= x2 + 5x – 10x – 10 + 5
= x2 – 5x – 5
Question 3 (vi)
−x2+10x−5 from 5x−10
Subtract-x2+10x-5 from 5x-10
(-10 x -10 x -10 x -10 x -10 x -10 x -10 x -10) divided by (-5 x -5 x -5 x -5 x -5) gives
