Question

(2x 2 +10x−2)−(−8x 2 +7x+7)

Answer 1

10xsquare + 3x −9

Explanation:

To substract the expression (2xsquare +10x - 2)-(-8xsquare+7x+7), you can distribute the negative sign inside the second set of brackets and then combine like terms:

(2x square +10x−2)−(−8xsquare+7x+7)=2xsquare+10x−2+8xsquare −7x−7

Now, you can combine like terms:

2x square+8x square+10x−7x−2−7=10x square+3x−9

So, the simplified expression is 10xsquare+3x−9
