dividing x2 + 3x + 1 by 3x2 and bringing down 13x.subtracting 3x4 + 9x3 + 3x2 from the dividend and bringing down 13x .multiplying 3x2 by x2 + 3x + 1.

⇒ -2

Complete the sentence below. If (3x2 + 22x + 7) ÷(x + 7) = 3x + 1, then (x + 7)() = . The check of the polynomial division problem shows that the product of two polynomials is a polynomial. This supports the fact that the property is satisfied for polynomial multiplication.
