Answer:
Real numbers = 39 and 9
Step-by-step explanation:
The standard form of a quadratic equation is ax² + bx + c = 0
Given the following data;
a = 1
b = -43
c = 306
Quadratic equation formula is;
Substituting into the equation, we have;
Therefore, the two real numbers are 39 and 9.
The quadratic equation now becomes;
x² – 43x + 306 = (x – 39)(x – 9) = 0
