Using synthetic division with $x - 5$, we bring down the leading coefficient (1 for $x^3$), multiply it by 5 (the root of $x - 5$), add it to the next coefficient (-75 for $x$), and continue this process. The result is $x^2 + 5x - 50$.

Use Synthetic Division to Divide (x3−75x+250)÷(x−5)\left( x ^ { 3 } - 75 x + 250 \right) \div ( x - 5 )(x3−75x+250)÷(x−5)

Use Synthetic Division to Divide $\left( x ^ { 3 } - 75 x + 250 \right) \div ( x - 5 )$
