Question

Find the quadratic polynomial if the zeros of its are 2 and -1 by 3 respectively

Answer 1

Answer:

we know that every quadratic equation is of the form

$a {x}^{2} + bx + c$

now,

$given \: zeroes \: are \: 2 \: and \: - \frac { 1}{3}$

we know that the sum of zeroes =-b/a

2-1/3=-b/a

5/3=-b/a (1)

product of zeroes =c/a

2×-1/3=c/a

-2/3=c/a (2)

from (1) and (2) ,we get

a=3,b= -5 and c= -2

$the \: equation \: will \: be \\ 3 {x}^{2} - 5x - 2$
