Question

the sum and product of quadratic polynomial are 20 and 12. the polynomial​

Answer 1

$we \: have \\ \alpha + \beta = 20 \\ \ \: \: \: \: \: \alpha \beta = 12 \\ but \: we \: know \: that \: \\ {x}^{2} - ( \alpha + \beta )x \: + \alpha \beta = 0 \\ \\ puting \: the \: above \: values \ \\ {x}^{2} - 20x \: + 12 = 0$

hope this helps you
