Q. 1 A3.7( 12 Votes )

# Which of the following is a quadratic polynomial?(i) 2 - x2 (ii) x+ (iii) x+ (iv) x2 +3 +2

(i) On solving the equations, Re-writing in the format of ax2 + bx + c = 0  b = 0 & c = 2

So, following the ideal pattern of a quadratic polynomial is a quadratic polynomial.

(ii) On solving the equations,

x+  it can’t be re-written in the format of ax2 + bx + c = 0

So, following the ideal pattern of a quadratic polynomial, x+ is not a quadratic polynomial.

(iii) On solving the equations,

x+ it can’t be re-written in the format of ax2 + bx + c = 0

So, following the ideal pattern of a quadratic polynomial, x+ is not a quadratic polynomial.

(iv) On solving the equations,

x2 + 3√x + 2 it can’t be re-written in the format of ax2 + bx + c = 0

So, following the ideal pattern of a quadratic polynomial, x2 + 3√x + 2 is not a quadratic polynomial.
