Functions and values
Functions are written as a function of unknown variables
Given the following functions
P(x) = −x² + 9x + 10
Q(x) = 12x
If the student earns the same profit, then;
P(x) = Q(x)
−x² + 9x + 10 = 12x
−x² + 9x + 10 - 12x = 0
x²+3x-10 = 0
Factorize
x²+5x - 2x - 10 = 0
x(x+5)-2(x+5) = 0
x = 2 and -5
It will take the students 2 days to earn the same profit and the non-viable answer is -5 since it is a negative value
