Question

Which of the following is equivalent to the polynomial expression below?

( 10g^3-8g^2+5g-14 ) + ( 10g^2+12g )
A: 10g^3 + 2g^2 + 17g-14

B: 10g^3 + 2g^2 + 17g - 14

C: 20g^3 + 2g^2 + 17g - 14

D: 20g^3 - 8g^2 + 17g-14

Answer 1

A

Explanation:

We just calculate and add it, make sure you get the right number, i also believe that the 17 in b should be 12 ( i have the same question in Algebra Nation)

Answer 2

Combine like exponents, so we have 10g^3 + 2g^2 + 17g -14.
Are A and B the same? Because it's one of those two.
