Answer:
Interpreting as: X=a-sqrt b X=a+sqrt b
Input:
X = a - sqrt(b) X = a + sqrt(b)
Alternate forms:
{a = (sqrt(b) + 1) X, a = X - sqrt(b), b = 0 ∨ X = -1}
{a = (sqrt(b) + 1) X, a + sqrt(b) = X, sqrt(b) (X + 1) = 0}
P=80 <---this is the answer
Answer:

Step-by-step explanation:
If we solve for 'x' variable, its recommended to multiply 'x' variable in both sides of inequality:
we have 
This is a quadratic equation, two answer are going to be obtained from here.
since 
Applying square roots to both sides of inequality sign we wil have the following

This leaves to the following

remember that 
so
