Q. Use synthetic division to find (7x2+3x10)÷(x1)(7x^2 + 3x - 10) \div (x - 1).\newlineWrite your answer in the form q(x)+rd(x)q(x) + \frac{r}{d(x)}, where q(x)q(x) is a polynomial, rr is an integer, and d(x)d(x) is a linear polynomial. Simplify any fractions.\newline______
  1. Set up synthetic division: Set up synthetic division with 11 as the zero of x1x - 1, and write the coefficients of 7x2+3x107x^2 + 3x - 10: 77, 33, 10-10.
  2. Bring down first coefficient: Bring down the 77 as the first coefficient of the quotient.
  3. Multiply and write result: Multiply 11 by 77 and write the result, 77, under the second coefficient, 33.
  4. Add second column: Add the second column: 3+7=103 + 7 = 10, and write the result below the line.
  5. Multiply and write result: Multiply 11 by 1010 and write the result, 1010, under the third coefficient, 10-10.
  6. Add third column: Add the third column: 10+10=0-10 + 10 = 0, and write the result below the line.
  7. Identify quotient and remainder: The numbers below the line are the coefficients of the quotient polynomial and the remainder. The quotient is 7x+107x + 10 and the remainder is 00.
