Step-by-step explanation:
Quadratic function is function of the form
where a, b and c are real numbers and 
A number is said to be a rational number if it can be written in the form
where u and v are integers and
.
A number is said to be a complex number if it can be written in the form u+iv where u and v are real numbers.
A number 'a' is said to be a zero of a function P(x) if 
We know that if zero of a fraction is of form u+iv then its other zero is u-iv.
As 3+7i is a zero of the function, 3-7i is also its zero.
So, given equation is
