1
Multiply the single term $x-4$ by each term of the polynomial $\left(x+1\right)$
$x\left(x-4\right)+x-4$
2
Multiply the single term $x$ by each term of the polynomial $\left(x-4\right)$
$x\cdot x-4x+x-4$
3
Apply the formula: $x\cdot x$$=x^2$
$x^2-4x+x-4$
4
Combining like terms $-4x$ and $x$
$x^2-3x-4$
Final answer to the problem
$x^2-3x-4$
