5p^2+7p+3=0

Solution for 5p^2+7p+3=0 equation:

Simplifying
5p2 + 7p + 3 = 0

Reorder the terms:
3 + 7p + 5p2 = 0

Solving
3 + 7p + 5p2 = 0

Solving for variable 'p'.

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

Divide each side by '5'.
0.6 + 1.4p + p2 = 0

Move the constant term to the right:

Add '-0.6' to each side of the equation.
0.6 + 1.4p + -0.6 + p2 = 0 + -0.6

Reorder the terms:
0.6 + -0.6 + 1.4p + p2 = 0 + -0.6

Combine like terms: 0.6 + -0.6 = 0.0
0.0 + 1.4p + p2 = 0 + -0.6
1.4p + p2 = 0 + -0.6

Combine like terms: 0 + -0.6 = -0.6
1.4p + p2 = -0.6

The p term is 1.4p.  Take half its coefficient (0.7).
Square it (0.49) and add it to both sides.

Add '0.49' to each side of the equation.
1.4p + 0.49 + p2 = -0.6 + 0.49

Reorder the terms:
0.49 + 1.4p + p2 = -0.6 + 0.49

Combine like terms: -0.6 + 0.49 = -0.11
0.49 + 1.4p + p2 = -0.11

Factor a perfect square on the left side:
(p + 0.7)(p + 0.7) = -0.11

Can't calculate square root of the right side.

The solution to this equation could not be determined.
