Question

a=3, b=-5, c=-11, d=-3,Obtain the quadratic or the cubic polynomial as the case may be in the standard form with the given coefficient.

Answer 1

A cubic polynomial is a polynomial of degree 3. The solutions of this equation are called roots of the polynomial f(x).

Now the general form of a cubic polynomial is ax³ + bx² + cx + d

Now all we have to do is put the values of all three coefficients and one constant.

The values given are as follows: a=3, b=-5, c=-11, d=-3,

(3 * x³) + (-5 * x²) + (-11 * x) + (3)

or, 3x³ - 5x² - 11x + 3. (Ans)

Answer 2

Hi ,

*************************************
Standard form of Cubic polynomial ,

ax³ + bx² + cx + d , a ≠ 0 ,
*************************************

Here ,

a = 3 , b = -5 , c = - 11 , d = - 3

Required Cubic polynomial ,

3x³ - 5x² - 11x - 3

I hope this helps you.
