Question

ਇਕ ਵਾਸਤਵਿਕ ਸੰਖਿਆ a, ਬਹੁਪਦ f(x) ਦਾ ਸਿਫਰ ਕਹਾਉਂਦੀ ਹੈ ਜੇਕਰ A real number a is called a zero of the polynomial f(x), if एक वास्तविक संख्या a को बहुपद f (x) का एक शून्य कहा जाता है, यदि

f(a) = –1

f(a)=1

f(a)=0

f(a) =–2

​

Answer 1

Step-by-step explanation:

Given:A real number a is called a zero of the polynomial f(x), if एक वास्तविक संख्या a को बहुपद f (x) का एक शून्य कहा जाता है, यदि

To find:

f(a) = –1

f(a)=1

f(a)=0

f(a) =–2

Solution:

A real number 'a' is called a zero of polynomial ;if by putting that value in the polynomial it will become zero ,

Thus

f(a)=0

एक वास्तविक संख्या a को बहुपद f (x) का एक शून्य कहा जाता है, यदि उस संख्या को बहुपद में रखने पर वह बहुपद शून्य हो जाता है अर्थात f(a)=0

Thus,

Option C is correct.

विकल्प C सही है |

For example:

$f(x) = {x}^{2} + 3x + 2$

One of the zero is -1.

put x=-1

$f( - 1) = ( { - 1)}^{2} + 3( - 1) + 2 \\ \\ = 1 - 3 + 2 \\ \\ f( - 1) = 3 - 3 \\ \\ f( - 1) = 0$
