If mean of two numbers a and b is 7 and ab = 45, find quadratic equation whose roots are a and b.

Answer 1

Answer:

Heya!!

Here is your answer....

Required quadratic equation in X is:-

x^2-(a+b)X+(ab)=0

a+b/2= 7.

a+b=7×2

a+b=14

And ab= 45. (Given)

= x^2-(14)X+(45)=0

So,x^2-14x+45=0 (Answer)
