The formula to calculate the Second Root of Quadratic Equation is:
x2=−(b)−√b2−4ac2a
Where:
The Second Root of Quadratic Equation is the value of one of the variables satisfying the given quadratic equation f(x), such that f(x2)=0.
Let's assume the following values:
Using the formula:
x2=−(8)−√82−4⋅2⋅(−42)2⋅2
Evaluating:
x2=−7
The Second Root of the Quadratic Equation is -7.
