Q. Use synthetic division to find (x2+x−2)÷(x+2).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 by writing the coefficients of x2+x−2, which are 1, 1, and −2. Then write the root of x+2, which is −2, to the left.
Bring down leading coefficient: Bring down the leading coefficient, which is 1.
Multiply and add coefficients: Multiply the root −2 by the leading coefficient 1 and write the result under the second coefficient.
Continue with multiplication and addition: Add the second coefficient 1 and the result of the multiplication −2×1, which is −2. Write the sum, which is −1, under the line.
Check for exact division: Multiply the root −2 by the new number −1 and write the result, which is 2, under the third coefficient.
Check for exact division: Multiply the root −2 by the new number −1 and write the result, which is 2, under the third coefficient.Add the third coefficient −2 and the result of the multiplication −2×−1, which is 2. Write the sum, which is 0, under the line.
Check for exact division: Multiply the root −2 by the new number −1 and write the result, which is 2, under the third coefficient.Add the third coefficient −2 and the result of the multiplication −2×−1, which is 2. Write the sum, which is 0, under the line.The numbers below the line represent the coefficients of the quotient polynomial q(x). Since there is no remainder, r is 0 and the division is exact.
