Question

p-2√p-15=0
solve for p.
simplify using radicals as needed, express complex numbers in terms of i.

Answer 1

We use quadratic formula
p= {2+or - sqrt[4-4*(1)(-15)] }/ 2
p ={2+or - sqrt[64] }/ 2
p = {2+- 8]/2
p = 10/2 or p = -6/2
p = 5 or -3

Answer 2

dang, apparently answer was 25. Thanks though!

Answer 3

that is because it should be
\[\sqrt{p}=5\]
