Question

in the standard form of quadratic polynomial, ax2 + bx + c, a, b and c are:

1) All Are Polynomials
2) All Are Rational
3) 'A' is Non Zero Real Number And B And C Are Any Polynomial.
4) All Are Integers.​

Answer 1

Answer:

a, b and c all are real numbers and a is not equal to zero. Option 3 is the correct answer but there is a small mistake - b and c are not any polynomial but instead they are real numbers.

Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

In the standard form of quadratic polynomial, ax² + bx + c , a, b and c are

a) All are real numbers.

b) All are rational numbers.

c) ‘a’ is a non zero real number and b and c are any real numbers.

d) All are integers.

EVALUATION

Here we have to find the standard form of quadratic polynomial

Let x be the variable involved

Since it is a quadratic polynomial

So the highest power of its variable that appears with nonzero coefficient is 2

Because it is a quadratic polynomial

So coefficient of x² is non zero

It is a real polynomial

So a , b , c are all real numbers

FINAL ANSWER

Hence the correct option is

c) ‘a’ is a non zero real number and b and c are any real numbers.
