Solution


Q.

The degree of polynomial having zeros –3 and 4 only is:
1 2  
2 1  
3 more than 3  
4 3  

Ans.

(1)

The degree of polynomial having zeros –3 and 4, i.e., only two zeros, is 2 because it will be a quadratic polynomial.

i.e., p(x) = (x – (–3))(x – 4) ⇒ p(x) = (x + 3)(x – 4) ⇒ p(x) = x² – x – 12, which is a polynomial of degree 2.
