(-8y^2+6y-1)+(-8y^2+8y+1)-(-3y^2+9y-9)

taurus [48]

The answer of the given equation is $-13y^{2} -11y+7$

Step-by-step explanation:

The given equation can be written as,

$(-8y^{2}+6y-1) +(-8y^{2}+8y+1)-(-3y^{2}+9y-9)$

= $-8y^{2} +6y-1-8y^{2}-8y -1+3y^{2}-9y+9$

[Taking same powered variables together we get,]

= $(-8y^{2}-8y^{2}+3y^{2}) +(6y-8y-9y)-1-1+9$

= $-13y^{2} -11y+7$

Here the answer.
