Question

ਪ੍ਰ:2. ਹੇਠ ਦਿਤੀਆਂ ਵਿਚੋਂ ਕਿਹੜਾ ਬਹੁਪਦ p(x) = (x+5)(x-2) ਦੀ ਇਕ ਸਿਫ਼ਰ ਹੈ ? Which of the following is a zero of the polynomial p(x) = (x+5)(x-2)? निम्नलिखित में से कौन सा बहुपद p (x) = (x +5) (x-2) का एक शून्य है ?


​

Answer 1

The zero of the polynomial is -5 and 2.

Step-by-step explanation:

The zero of the polynomial is defined as any real value of x, for which the value of the polynomial becomes zero.

Given polynomial is:

p(x) = (x+5)(x-2)

To find the zero of this polynomial:

 p(x) = 0

So x+5 = 0

   x = -5

   x-2 = 0

   x = 2

The zero of the polynomial is -5 and 2.

(x+5) and (x-2) are the roots of the polynomial.

Answer 2

$\displaystyle\huge\red{\underline{\underline{Solution}}}$

TO DETERMINE

The zeros of the polynomial p(x) = (x+5)(x-2)

CALCULATION

Here

$\sf{ p(x) = (x + 5)(x - 2)\: \: }$

For Zero of the polynomial p(x) we have

$\sf{ p(x) = 0\: }$

$\implies \: \sf{ ( x+ 5)(x - 2) = 0\: }$

$\sf{Either \: \: \: x + 5 = 0 \: \: or \: \: x - 2 = 0\: \: }$

$\sf{ x + 5 = 0 \: \: gives \: \: x = - 5\: }$

$\sf{ \: x - 2 = 0 \: \: \: gives \: \: x = 2 \: }$

RESULT

The zeros of the polynomial is - 5 & 2
