Question

Quizplus · Accepted Answer

The synthetic division of $x^2 - 49$ by $x - 7$ results in $x + 7$, because when you substitute $x = 7$ into the divisor, the remainder is 0, indicating that $x - 7$ is a factor of $x^2 - 49$, and the quotient is $x + 7$.

Use Synthetic Division to Divide (x2−49)÷(x−7)\left( x ^ { 2 } - 49 \right) \div ( x - 7 )(x2−49)÷(x−7)
