Question 104

A scientist is modeling the growth rate VVV of a bacterial colony in terms of the concentration of a specific nutrient xxx. The relationship for x>0x > 0x>0 and x≠49x \neq 49x=49 is given by:

V=10.5+7x−1.5x12−x327−x V = \frac{10.5 + 7x - 1.5x^{\frac{1}{2}} - x^{\frac{3}{2}}}{7 - \sqrt{x}} V=7−x​10.5+7x−1.5x21​−x23​​

Fully simplify the expression for VVV, justifying each step of your factorisation.
