Option D: Two irrational solutions
Explanation:
The equation is 
Subtracting 6x from both sides, we have,

Solving the equation using quadratic formula,

Simplifying the expression, we get,

Taking out the common terms and simplifying, we have,

Dividing by 3, we get,

Hence, the equation has two irrational solutions.
You can make it with 10 because 10%times 5% is 50%
Take notes and pay attention since just slacking off for only 10 minutes can get you behind and struggling.
