The answer is -3x^2+10xy+8y^2
0.326= 326/1000
0.326= 163/500
0.326= 32.6%
(x-9) (x+2)=x²+2x-9x-18=x²-7x-18
First, multiply -6*-5. This equals (positive) 30 because the negative signs cancel out.
This leaves you with:
30+12
Doing the addition leaves you with 42.
The answer is 42.
I hope this helps :)
