All to one side:
4x^2-32x+64 = 0,
divide by 4:
x^2 -8x + 16 = 0
apply formula or see that it is (x-4)^2!, so only x =4 is a root and it is double.
Answer could be this 2x^2 - 7x + k/ x in a fraction with x being the only thing at the bottom btw

Answer:
Equation: 
when n = 4
Step-by-step explanation:
Given
Direct Variation: P ∝ n
When n = 15, P = 150
Required
Determine the equation
Her earnings if she sold 4 necklaces
P ∝ n
Convert variation to equation

When P = 150, n = 15 (Substitute these values in the given equation)

Divide both sides by 15


Substitute k = 10 in 

------- Equation that relates P and n
When she sold 4 necklaces, n = 4
Substitute n = 4 in the formula above
