Question

find a quadratic polynomial sum and product of whose 0 and -1 and -20 respectively ​

Answer 1

Step-by-step explanation:

sum of zeros= -1

product of zeros= -20

equation of quadratic polynomial is

$p(x) = k({x}^{2} -( \alpha + \beta )x + \alpha \beta )$

$p(x) = k( {x}^{2} - ( - 1)x + ( - 20))$

put k=1

$p(x) = {x}^{2} + x - 20$
