Question

3) Find a quadretic polynomail when the sum and the product is spectivity are - 1/2 - 10/2 ​

Answer 1

Answer:

Answer

We know that every quadratic equation is based on this relation..

p(x)=kx²−(α+β)x+αβ

where, α and β are the zeroes of given polynomial.

Now putting values of (α+β)=2 and αβ=−15 in above equation, we get ...

p(x)=x²−2x−15=0
