Simplify 3m/m-6 * 5m^3-30m^2/5m^2

This is your answer. If you still need it:

3m/m-6 * 5m^3-30m^2/5m^2

First you need to put the numerators and the denominators together in the same "line" or "fraction if you would say.

(3m) (5m^3-30m^2) / (m-6) (5m^2)

Then you would use the distributive property and then multiply the expressions. No dividing yet.

15m^4-90m^3/5m^3-30m^2

Now you simplify with the power of exponents rule

15m-90m/5-30

Now you normally simplify by just subtracting

-75m/-25

Then simply simplify the constants

3m (The answer is 3m because - 75/-25=3 positive whole numbers always stay on top [numerator], if it were negative and still on the denominator, using power of exponent rules, you would switch it up to the numerator, or "flipping" the constant or variable)

-30m^3-3 here is your answer
