The roots of the equation f(x) = x^2 – 93987 are x = √93987 and x = -√93987

Quadratic equations are equations that have a second degree and have the standard form of ax^2 + bx + c = 0, where a, b and c are constants and the variable a does not equal 0

### How to determine the other roots of the equation?

The equation of the function is given as:
f(x) = x^2 – 93987
The above equation is a quadratic equation
Express the equation as a difference of two squares
f(x) = (x – √93987)(x + √93987)
Set the equation of the function to 0
(x – √93987)(x + √93987) = 0
Split the factors of the above function equation as follows
x – √93987 = 0 and x + √93987 = 0
Solve for x in the above equations
x = √93987 and x = -√93987
Hence, the roots of the equation f(x) = x^2 – 93987 are x = √93987 and x = -√93987
