Q. Use synthetic division to find (x2−7x+12)÷(x−4).Write your answer in the form q(x)+d(x)r, where q(x) is a polynomial, r is an integer, and d(x) is a linear polynomial. Simplify any fractions._________
Set up synthetic division: Set up synthetic division with 4 as the root from x−4 and the coefficients of x2−7x+12 as 1, −7, and 12.
Perform synthetic division: Perform synthetic division: Bring down the leading coefficient 1. Multiply 4 by 1 and write the result 4 under \$\(-7\)\). Add \$\(-7\)\) and \(4\) to get \$\(-3\)\). Multiply \(4\) by \$\(-3\)\) and write the result \$(\(-12\))\) under \(12\). Add \(12\) and \$\(-12\)\) to get \(0\).
Write the result: Write the result of synthetic division. The quotient is \(x - 3\) and the remainder is \(0\).
Express the result: Express the result as \(q(x) + \frac{r}{d(x)}\). Since the remainder is \(0\), the result is simply \(q(x)\), which is \(x - 3\).
