The answer would be -6x^2-9x-19

Because firstly you distribute the negative sign

2x^2 -9x-6+-1(8x^2+7+6)

2x^2+-9x+-6-1(8x^2)+(-1)(7)+(-1)(6)

2x^2+-9x+-6+-8x^2+-7+-6

And combine like terms

(2x²-9x-6) - (8x²+7+6)

let us distribute the negative sign over the second bracket first,

2x²-9x-6 - 8x²-7x-6

Now combining like terms

-6x²-16x-12
