Form the quadratic equation from the roots given below. (2) 3 and -10​

Answer»

Answer:

3 and 10 are roots

let these TWO roots be

\alpha  \: and \:  \beta

\alpha  = 3 \: and \:  \beta  = 10

the structure of quadratic EQUATION is

{x}^{2} - (sum \: of \: roots)x + product \: of \: roots

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

\alpha  +  \beta  = 3 + 10 = 13

\alpha  \beta  = 3 \times 30

•°• the equation is

{x}^{2} - 13x + 30
