Answer :
When the polynomial (2x³+4x² - 9x -18) is divided by x+5, the quotient is 2x²-6+21 and the remainder is -123/(x+5).
What is polynomial?
Polynomials are sums of k-x^n terms, where k can be any number and n can be any positive integer. 3x+2x-5, for example, is a polynomial. Polynomials are introduced. This video defines words such as degree, standard form, monomial, binomial, and trinomial. A polynomial is an equation made up of variables, constants, and exponents that are mixed using mathematical operations including addition, subtraction, multiplication, and division (No division operation by a variable).
Here,
Dividend=(2x³+4x² - 9x -18)
Divisor=(x+5)
On dividing them using long division,
quotient=2x²-6+21
remainder=-123/(x+5)
The quotient is 2x²-6+21 and remainder is -123/(x+5) for the polynomial (2x³+4x² - 9x -18) when divided by x+5.
