That may be why it didn't look right to you.

Thanks. I thought I was doing it wrong when I was adding the exponents. Looks like I did it right.
I will have more questions ove rht enext couple days though. This course will be the end of me.

Predaprince wrote:I see a very common mistake that my Algebra 1 students constantly make. When you multiplied (12x-5)(3x^2-5)-(6x^2-5x+1)(6x), you forgot that the minus sign needs to be "distributed" to all parts of the second product.
You should now have
36x^3-60x-15x^2+25-36x^3+30x^2-6x
9x^4-15x^2-15x^2+25
15x^2 - 66x + 25
9x^4 - 30x^2 + 25

And I haven't done this level of math in about 15 years!

Just wait until my questions about multivirate calculus start up.
