Answer:

Hence the expression $$(5x-y)(x-4)=5x^2-xy-20x+4y$$

Step-by-step explanation:

Explanation

  • The given expression is (5 x-y)(x-4).
  • We have to multiply the given expression.
  • Multiply the (5 x-y) by -4, multiply the (5 x-y) by x then add like terms.

$$\begin{matrix}{} & {} & {} & {} & 5x & - & y \\ \times & {} & {} & {} & x & - & 4 \\ \end{matrix}$$

_________________

$$\begin{matrix}{} & {} & {} & - & 20x & + & 4y \\ 5{{x}^2} & - & xy & {} & {} & {} & {} \\ \end{matrix}$$

_________________

$$\begin{matrix}5{{x}^2} & - & xy & - & 20x & + & 4y \\ \end{matrix}$$
