There are certain rules of writing math texts and math equations, in particular.

Mixing words and math symbols, when you write an equation, is the same as mixing English and Chinese in one phrase.

This is ambiguous: 
square root of (3p^2 - 11) - x = 0 
If p > 0 and x = 8 in the equation above,...



Assuming you really have sqrt%283p%5E2-11%29-8=0, based on the way your parentheses appear, then you need 3p%5E2-11%3E=0 but also sqrt%283p%5E2-11%29=8. The equation is important.

Square both sides of that last form.
3p%5E2-11=64
3p%5E2=64%2B11=75
p%5E2=75%2F3=25
For the positive p, highlight%28p=5%29.
