Question

यदि बहुपद P (x) = x2-23x + 5 के शून्यक a, b हो, तो ab का मान क्या होगा?​

Answer 1

SOLUTION

TO DETERMINE

If a and b are the zeroes of the polynomial P(x) = x² - 23x + 5 then the value of ab is

EVALUATION

Here the given polynomial is

P(x) = x² - 23x + 5

We know that If the roots of a quadratic polynomial are given then the quadratic polynomial is

$\sf{ {x}^{2} -(Sum \: of \: the \: zeroes )x + Product \: of \: the \: zeroes}$

Thus we get

Sum of the zeroes = a + b = 23

Product of the zeroes = ab = 5

FINAL ANSWER

Hence the required value of ab = 5
