Question

The quotient of 16 and the difference of a number and 3 is 4 more than the same number cubed

Answer 1

Answer:

x  = -1 is one solution of the equation.

Another solution is x $\approx$ 3.13

Step-by-step explanation:

i) let the require number be x

ii) therefore from the problem we can write the equation

$\frac{16}{x-3} = 4x^{3}$

Therefore $4x^4 - 12x^3 - 16 = 0$

On inspection we can see that x  = -1 is one solution of the equation.

Another solution is x $\approx$ 3.13
