Question

How do you simplify `6h ^ { 2} - 4h ^ { 2} + 6+ 3`?

Answer 1

Collect like terms

`2h^2+9`

Answer 2

`2h^2+9`

Explanation:

Since this is just an expression (there is no = sign), we can simply combine like terms.

`6h^2` and `4h^2` have the same base (h) and exponent (2), and can therefore be combined.

`6h^2-4h^2=2h^2`

`6+3=9` (6 and 3 are like terms because they have the same exponent and base)
