Question

Simplify the following expression.
2x - 6y + 3x2 + 7y - 14x.

3x2 + 12x + y

3x2 - 12x - y

3x2 - 12x + y

3x2 - 12x - 13y

Answer 1

On 3x2 it is 3x^2

Answer 2

combine the y terms and the x terms :)

Answer 3

Exactly what yum said

Answer 4

12x +3x^2 + 1y

Answer 5

\[2x - 6y + 3x^2 + 7y - 14x\]rearrange:\[3x^2-14x+2x-6y+7y\]combine like terms:\[3x^2-12x-6y+7y\]\[3x^2-12x+y\]and there ya have it!

Answer 6

now remember its a NEGATIVE 14 added to a POSITIVE 2...so that's NEGATIVE 12 :)

Answer 7

So, 3x^2 -(-12) + y ?

Answer 8

so your answer is C. 3x^2-12x+y

Answer 9

no it's not minus negative, its just 3 x squared minus 12 x plus y :)

Answer 10

Oh Thank you so much!

Answer 11

No problem! :D
