Question

Please tell with full explanation T-T

Answer 1

Alright, this question has two parts

First, we find the sum of

$(4 + 3x) + (5 - 4x + 2x^2)$ ...(1)

and then the sum of

$(3x^2 -5x)+(-x^2+2x+5)$ ...(2)

Then we subtract one from the other >_<

Alright, let's solve (1)$2x + 4$

$4 + 5 + 3x - 4x + 2x^2$

$9 - x + 2x^2$

$2x^2 - x + 9$

Now, (2)

$3x^2 - x^2 -5x + 2x + 5$

$2x^2 - 3x + 5$

Now, the final step (1) - (2)

=

$2x^2 - x + 9 -(2x^2 - 3x + 5)$

$2x^2 - x + 9 -2x^2 + 3x - 5$

$2x^2 - 2x^2 -x + 3x + 9 - 5$

$2x+4$

Hope this Helped!
