(-9x^3+3x^2-15x)?(-3x)
Is the ? divided by??
If so you are dividing a trinomial by a monomial
you just divide each term of the trinomial by the monomial
-9x^3 divided by -3x
3x^2 divided by -3x
-15x divided by -3x
Remember to divide the coefficients (numbers out in front)
Then for the x's with the exponents. Keep the x and subtract the exponents.
The first one will have x^2 in the answer.
Do you need more help or are you okay now?
To find the product of (-9x^3 + 3x^2 - 15x) and (-3x), we will use the distributive property of multiplication over addition.
First, distribute the -3x to each term in the parentheses:
(-3x)(-9x^3) + (-3x)(3x^2) + (-3x)(-15x)
This simplifies to:
27x^4 - 9x^3 - 45x^2
So, the product of (-9x^3 + 3x^2 - 15x) and (-3x) is 27x^4 - 9x^3 - 45x^2.
