$-20k^2+15k$

#### Work Step by Step

We can multiply a monomial by a polynomial using the distributive property, which states that we multiply the term outside the parentheses by each term inside the parentheses and then combine like terms to simplify: $$5k(3-4k)=3(5k)-(4k)(5k)=15k-20k^2$$To write in standard form, the term with the highest power must come first. This gives us: $-20k^2+15k$
