Respuesta :
(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
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
