Question

Consider the quadratic equation whose roots are 5 and -4

Answer 1

Hi ,

********************
Quadratic Equation of whose roots

are p anq is

x² - ( p + q )x + pq = 0

**************"******

Here ,

p = 5 , q = -4

Sum of the roots = 5 + ( - 4 )

p + q = 5 - 4 = 1

Product of the roots = 5 ( - 4 )

pq = - 20

Therefore ,

Required equation

x² - 1x -20 = 0

I hope this helps you.
