The negative sign is NOT included in the square function

You have 3h*(-h^{2}) NOT 3h*(-h)^{2}

asked • 01/11/19I have to solve this:

3h × (-h^{2 })

When I tried it, I got 3h^{3} as a result, yet the answer key says it should be -3h^{3 }I don't understand why 3 becomes negative.

My logic was the following: -h^{2} is the same as h^{2} (because negative multiplied by negative equals positive). Therefore the problem becomes 3h × (h^{2 }) and that is the same as 3 × h × h^{2} We can add the exponents and get h^{3}. Therefore the answer is 3h^{3}. What am I doing wrong?
