The zeros of f(x) = x^2 - x - 30 are x = 6 or -5
How to determine the zeros?
The function is given as:
f(x) = x^2 - x - 30
Expand
f(x) = x^2 + 5x - 6x - 30
Factorize the function
f(x) = x(x + 5) - 6(x + 5)
Factor out x + 5
f(x) = (x - 6)(x + 5)
Set to 0
(x - 6)(x + 5) = 0
Solve for x
x = 6 or -5
Hence, the zeros of f(x) = x^2 - x - 30 are x = 6 or -5
