Question

Find the quadratic polynomial if a + b = 1/4 and aß =-1(given)

​

Answer 1

Answer:

sol.given that

the sum of zero(a+b)=1/4

the product of zero (ab)=-1

I.Q.P with zero a,b then

=k[x^2-(a+b)X+ab]

=k[x^2-1/4x+(-1)]

let k=4 then

=4[x^2-x/4-1]

=4.x^2-4.x/4-4

=4x^2-x-4

: quadratic polynomial=4x^2-x-4
