Question

Find the quadratic polynomial whose sum of zeroes is 10 and the product is -39.​

Answer 1

Answer:

x2-10x-39 is the quadratic Equation

Answer 2

Answer:

let px²+qx+r=0 is a quadratic equation.

let a and b are two zeroes of this equation.

As per question,

a+b=(-q/p)=10

So q/p=(-10).......(i)

ab=(r/p)=(-39).......(ii)

Now dividing p on both sides of quadratic equation we get,

x²+(q/p)x+(r/p)=0........(iii)

Putting the values of equations (i) and (ii) in equation (iii) we get,

x²-10x-39=0

This is the required equation.

If my answer satisfies you then give me thanks.
