Answer:
there is only one easy way to sole this
using quadratic equation

Step-by-step explanation:
a=6 b=5 c=-6
and by applying it to the equation you will get
x=0.66 and x=-1.5
If you are asking how to subtract 125 centimeters and make it 87.5, you have to subtract from 125. The easiest way to do this is to subtract 87.5 from 125, getting 37.5. So, if you add 37.5 to 87.5, you will have 125. So, the correct answer is to subtract 37.5 to get 87.5.
Hope this helps you:)
