Answer:
Converting the equation
into completing the square method we get: 
Step-by-step explanation:
we are given quadratic equation: 
And we need to convert it into completing the square method.
Completing the square method is of form: 
Looking at the given equation 
We have a = x
then we have middle term 20x that can be written in form of 2ab So, we have a=x and b=? Multiplying 10 with 2 we get 20 so, we can say that b = 20
So, 20x in form of 2ab can be written as: 2(x)(10)
So, we need to add and subtract (10)^2 on both sides

So, converting the equation
into completing the square method we get: 
He used an incorrect time ratio converting hours to minutes.
