Steps to solve:
5x² = 15x
~Subtract 15x to both sides
5x² - 15x = 15x - 15x
~Simplify
5x² - 15x = 0
~Factor left side
5x(x - 3) = 0
~Factors equal 0
5x = 0 and x - 3 = 0
___________
~Simplify 5x = 0
5x/5 = 0/5
x = 0
~Simplify x - 3 = 0
x - 3 + 3 = 0 + 3
x = 3
___________
Thus, the correct answer is 0, 3.
___________

D is the ans. Square root of 49 equals to 7
The graph has domain x ∈ ( 0 , +∞ )
It is first increasing and then decreasing. It has a local minimum and a global maximum.
- x^4 + x³ + 7 x² - x - 6 = ( x - 1 ) ( x + 1 ) ( x + 2 ) ( 3 - x )
The company will break even when P ( x ) = 0
The zeroes are: x 1 = 1, x 2 = 3
The company has a profit when: x ∈ ( 1, 3 )
