Question

Obtain linear, quadratic and cubic polynomial if a=6,b=-7,c=-3
Please guys help me. I am stuck now. ​

Answer 1

Answer:

cubic polynomial is a polynomial of degree 3, or in simplier terms highest power of x is 3.

It is of the form f(x)=ax

3

+bx

2

+cx+d where a,b,c,d belongs to real numbers.

We can see that in option A, a=1,b=3,c=−4 and d=3.

Rest of the options B, C, D have the highest degree as 2.

Hence, they are quadratic polynomials.

Answer 2

Answer:

linear equation _ ax + b =0

6x+7=0

quadratic _ax² + bx + c=0

6x² + 7x+ 3=0

cubic _ ax³+bx²+cx+0=0

6x³+7x²+3x +0=0
