Question

Simplify: (3x2 − 2) + (5x2 + 5x − 1)

Answer 1

for this you want to combine "like Terms"

Answer 2

can you right it out and i do the work?

Answer 3

sure you have a 3x^2 and a 5x^2, since they both have the similar term x^2 you can combine those
you have a 5x, but nothing else with just an 'x' as a variable so that stays 5x and finally you have -2 + -1, so just add those terms

Answer 4

-3?

Answer 5

exactly

Answer 6

so your final answer is?

Answer 7

2x^2 +5x=-3

Answer 8

i think the parenthesis are messing you up...what if you looked at it like this?
3x^2 + 5x^2=
5x
-2 + -1=

Answer 9

8x2 + 5x − 3? or 2x2 + 5x − 3?

Answer 10

youre adding 3x^2 PLUS 5x^2 so 3+5= 8x^2
so youre final answer is: 8x^2 +5x -3

Answer 11

thank you!!!!

Answer 12

no problem, just remember when adding/subtracting to combine like terms!
