Answer:
Step-by-step explanation:
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
63 - 2.95 = 60.05
Rounding using significative figures
63 has three significative figures
2.95 has three
So, we must round the result to 2 significative figures.
Result = 60
