What is the missing coefficient?

For this case we have the following expression:

$(15x ^ 2 + 11y ^ 2 + 8x) - (7x ^ 2 + 5y ^ 2 + 2x) =$

We eliminate the parentheses taking into account that:

$- * + = -\\15x ^ 2 + 11y ^ 2 + 8x-7x ^ 2-5y ^ 2-2x$

We add similar terms:

$15x ^ 2-7x ^ 2 + 11y ^ 2-5y ^ 2 + 8x-2x =$

Different signs are subtracted and the sign of the major is placed:

$8x ^ 2 + 6y ^ 2 + 6x$

Finally, the expression is reduced to:

$8x ^ 2 + 6y ^ 2 + 6x$

Answer:

$8x ^ 2 + 6y ^ 2 + 6x$
