Answer 3

To perform the arithmetic operation, you need to simplify the expression:

$6x^2 + 7x - 3 - (15x^2 + x - 2)$

To do this, first distribute the negative sign to the terms inside the parentheses:

$6x^2 + 7x - 3 - 15x^2 - x + 2$

Next, combine like terms:

$(6x^2 - 15x^2) + (7x - x) + (-3 + 2)$

$= -9x^2 + 6x - 1$

So, the simplified expression is $-9x^2 + 6x - 1$.
