Assertion: The degree of polynomial is (x-2)(x-3 )(x+4) is 4. Reason:The number of zeros of polynomial is the degree of that polynomial . i) Assertion is true but reason is is false ii)Assertion is false but reason is true iii)Assertion is true ,reason is also true iv) Assertion is false, reason is also false​

Answer 1

Given :  

Assertion: The degree of polynomial is (x-2)(x-3 )(x+4) is 4.

Reason:The number of zeros of polynomial is the degree of that polynomial

To Find : Choose correct option

Solution:

Assertion: The degree of polynomial is (x-2)(x-3 )(x+4) is 4.  FALSE

(x-2)(x-3 )(x+4)

= (x - 2)(x²  + x - 12)

= x³ - x² -14x + 24

Degree of a polynomial is the highest power of variable in the polynomial.

Here  highest power is 3

Hence its degree is 3 not 4

Hence Assertion is FALSE

Reason: The number of zeros of polynomial is the degree of that polynomial

FALSE

as  x² +  4   does not have any real zero but degree is 2.

Hence

Assertion is false, reason is also false​
