Answer 1

Simplify.

2m2 – 4n2 + 3m – 6m2 – 2m + 7n2

A.
−4m2 + 3n2 + m

B.
−4m2 + 3n2

C.
–36m + 28n

D.
9m2 + 6m + 11n2

Answer 2

HI!!

Answer 3

identify the like terms, then combine them!

Answer 4

the nubers at the end are veriables

Answer 5

Find the like terms first.

\(2m^2\) and \(-6m^2\)

\(-4n^2\) and \(7n^2\)

\(3m\) and \(-2m\)

Can you combine these? It's just like adding regular numbers, but we keep the variable and exponent.

So like if we have:

\(6x^2 + 5x^2\) it becomes \(11x^2\), because 6 + 5 = 11.

Answer 6

ok.

Answer 7

So first add \(2m^2 + -6m^2\)

Answer 8

2m2 + -6m2 =-4m2 -4n2+ 7n2 = 3n2 3m + -2m = 1m

Answer 9

so a?

Answer 10

Looks good!

Answer 11

Yep, A is correct!

Answer 12

thank you.
