Answer:

you have to find the smallest common denominator

Step-by-step explanation:

so once the fractions have the same denominator you can add them easily and simplify

(−14x^3y^3+4x^5 y6)÷(2x^4y^5)

valkas [14]

( - 14x^3)(y^3) + 4x^5y^6)/(2x^4y^5)

= 4x^5y^6 - 14x^3y^3/2x^4y^5

= 4x^2y^3 - 14/2xy^2

= 2x^2y^3 - 7/xy^2

Answer: 2x^2y^3 - 7/xy^2

Hope that helps!!!!

Zero of 7 with a multiplicity of 3 means one factor is $(x-7)^3$

Zero of -1 with a multiplicity of 2 means one factor is $(x+1)^2$

Zero of 5 with a multiplicity of 1 means one factor is $(x-5)$

Multiplying, we get

$f(x) = (x-7)^3(x+1)^2(x-5)$

That's already in factored form so we leave it here.
