Question

Which is equivalent to the polynomial

Answer 1

The correct solution is "
`10g^3+2g^2+17g-14`".

Explanation:

The given expression is:

=
`(10g^3-8g^2+5g-14)+(10g^2+12g)`

By opening the brackets, we get

=
`10g^3-8g^2+5g-14+10g^2+12g`

By applying addition and subtraction, we get

=
`10g^3+2g^2+17g-14`

Or,

The expression isn't a perfect cube.
