Q no 9 pls
Q.9. Form a quadratic polynomial with sum and product of zeroes are 2 and -3/5 respectively.
Ans : k $\left(5x^2-10x-3\right)$

Please find below the solution to the asked query:

Given :  Sum of zeroes = 2 and product of zeroes  = $-\frac{3}{5}$

We know polynomial = k [ x² - ( Sum of zeroes ) + ( Product of zeroes ) ]  ,  Here ' k '  is any integer .

So,

Given polynomial = $k\left[x^2 - 2 x-\frac{3}{5}\right] = k\left[\frac{5 x^2 - 10 x-3}{5}\right] = \mathbf{ }\mathit{k}\left[\mathbf{5}\mathbf{ }{\mathbf{x}}^{\mathbf{2}}\mathbf{ }\mathbf{-}\mathbf{ }\mathbf{10}\mathbf{ }\mathbf{x}\mathbf{-}\mathbf{3}\right]\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{(}\mathbf{ }\mathbf{Ans}\mathbf{ }\mathbf{)}$
