Answer:

बहुपद x2 – 3 के शून्यक ज्ञात कीजिए और शून्यकों तथा गुणांकों के बीच के संबंध की सत्यता की जाँच कीजिए। ... हल : माना द्विघात बहुपद ax' + bx + c है और इसके शून्यक a और 8 हैं। यदि a = 1 है, तो b = 3 और c = 2 होगा।

Answer:

x^{2} - (a+ b)x + ab is the required quadratic polynomial

Step-by-step explanation:

Explanation :

Given , a and b are the zeroes of the quadratic equation .

A quadratic polynomial is a quadratic polynomial. That is, the maximum exponent of the variable is 2.

Let one zero of the polynomial (a) be \alpha

and other zero (b) be \beta

Step 1:

Therefore , product of zeros = \alpha \beta = ab

and sum of zeroes = \alpha +\beta = a+b

But we know that  ,

P(x) = x^{2} - (\alpha +\beta )x + \alpha \beta

Now put the value of (\alpha +\beta ) and \alpha \beta in the above equation

x^{2} - (a+ b)x + ab

Final answer :

Hence , the quadratic polynomial is x^{2} - (a+ b)x + ab
