Solution, \left(2x^2+4x-9\right)-\left(3x^2-2x+10\right)=-x^2+6x-19

Steps:

\mathrm{Remove\:parentheses}:\quad \left(a\right)=a, =2x^2+4x-9-\left(3x^2-2x+10\right)

-\left(3x^2-2x+10\right):\quad -3x^2+2x-10\\

=2x^2+4x-9-3x^2+2x-10\mathrm{Simplify}\:2x^2+4x-9-3x^2+2x-10:\quad -x^2+6x-19, =-x^2+6x-19

Probability models<br> Please help
Natasha2012 [34]
I believe the answer is 28/40 which is reduced to 7/10.

It says large OR blue, so i added the total of large + blue, and its out of 40 total so i got 28/40. that reduces to 7/10.
