Question

Simplify (3x^2-2x+1)-(x^2-2x-3)+(4x^2-x+2)
A.) 6x^2-x+6
B.) 6x^2-5x+6
C.) 6x^2-x
D.) 8x^2-5x+6

Answer 1

All you do is add up all the coefficients with equal powered x's

Answer 2

u have to combine like terms first

Answer 3

write it like this:

3x^2-2x+1-x^2+2x+3+4x^2-x+2

collect like terms.

Answer 4

3x^2-2x+1-x^2+2x+3+4x^2-x+2
=6x^2-x+6

Answer 5

Not suppose to give out answers.

Answer 6

idk how to explain , sorry

Answer 7

Would you do 3x^2-x^2 and get 2x^2, and then add the 4x^2 to get 6x^2?

Answer 8

yes but its more safe if u add the all negative and positive before you add and minus
like 4x^2+ 3x^2 = 7 x^2 before u minus the x^2= and u can get 6x^2

Answer 9

Ohh okay, I get it now. Thanks ! :)
