Please explain number 17 that is the answer on this picture but I cannot understand it I need this done tonight you will get Brainly

Answer 1

Answer:

$x^{2} +2y^{2} +8xy$

Step-by-step explanation:

$6x^{2} -4xy + 2y^{2} -5x^{2} +2xy+10xy$

Okay, so of course you need to add like terms. But where should you start? Well, $6x^{2}$ and $-5x^{2}$ are both like terms, so lets add them first.

$6x^{2} -5x^{2} = x^{2}$

Also, $-4xy$, $2xy$, and $10xy$ are like terms, so we can add them together too.

$-4xy + 2xy +10xy = 8xy$

There isn't anymore like terms, so now we need to put it in simplest form.

$x^{2} +2y^{2} +8xy$

Hope this helps! I actually think 2y^2 is before x^2 in the answer, but unless you need it in simplest form it shouldn't matter. Review with your teacher before turning in if you can. :))
