Question

What is the sum of $negative 2 straight x squared plus 3 straight x – 4$ and $3 straight x squared – 4 straight x plus 6$ ?

$x^{4} - x^{2} + 2$
$5 x^{4} + 7 x^{2} + 10$
2
$x^{2} - x + 2$

hint Hint:

Combine like terms.

The correct answer is: $straight x squared – straight x plus 2$

$negative 2 straight x squared plus 3 straight x – 4$ + $3 straight x squared – 4 straight x plus 6$
$equals left parenthesis negative 2 straight x squared plus 3 straight x squared right parenthesis plus left parenthesis 3 straight x – 4 straight x right parenthesis plus left parenthesis negative 4 plus 6 right parenthesis equals straight x squared – straight x plus 2$

Which expression is equivalent to $left parenthesis straight x squared plus 3 straight x – 5 right parenthesis – left parenthesis 4 straight x squared plus 3 straight x – 6 right parenthesis ?$
