Solution for 2p^2+5=p equation:


Simplifying
2p2 + 5 = p

Reorder the terms:
5 + 2p2 = p

Solving
5 + 2p2 = p

Solving for variable 'p'.

Reorder the terms:
5 + -1p + 2p2 = p + -1p

Combine like terms: p + -1p = 0
5 + -1p + 2p2 = 0

Begin completing the square.  Divide all terms by
2 the coefficient of the squared term: 

Divide each side by '2'.
2.5 + -0.5p + p2 = 0

Move the constant term to the right:

Add '-2.5' to each side of the equation.
2.5 + -0.5p + -2.5 + p2 = 0 + -2.5

Reorder the terms:
2.5 + -2.5 + -0.5p + p2 = 0 + -2.5

Combine like terms: 2.5 + -2.5 = 0.0
0.0 + -0.5p + p2 = 0 + -2.5
-0.5p + p2 = 0 + -2.5

Combine like terms: 0 + -2.5 = -2.5
-0.5p + p2 = -2.5

The p term is -0.5p.  Take half its coefficient (-0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
-0.5p + 0.0625 + p2 = -2.5 + 0.0625

Reorder the terms:
0.0625 + -0.5p + p2 = -2.5 + 0.0625

Combine like terms: -2.5 + 0.0625 = -2.4375
0.0625 + -0.5p + p2 = -2.4375

Factor a perfect square on the left side:
(p + -0.25)(p + -0.25) = -2.4375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
