Any two quadratic equations.
Solution:
The general form of a quadratic equation is:
Where, a,b and c are real number and a is non zero.
We know that a,b,c can take any values but a cannot be 0.
For a=1, b=1,c=1, we get
One quadratic equation is .
For a=3,b=-1,c=5, we get
Therefore, the two quadratic equations are and
