5m^2+17m+15=

Solution for 5m^2+17m+15= equation:

Simplifying
5m2 + 17m + 15 = 0

Reorder the terms:
15 + 17m + 5m2 = 0

Solving
15 + 17m + 5m2 = 0

Solving for variable 'm'.

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

Divide each side by '5'.
3 + 3.4m + m2 = 0

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + 3.4m + -3 + m2 = 0 + -3

Reorder the terms:
3 + -3 + 3.4m + m2 = 0 + -3

Combine like terms: 3 + -3 = 0
0 + 3.4m + m2 = 0 + -3
3.4m + m2 = 0 + -3

Combine like terms: 0 + -3 = -3
3.4m + m2 = -3

The m term is 3.4m.  Take half its coefficient (1.7).
Square it (2.89) and add it to both sides.

Add '2.89' to each side of the equation.
3.4m + 2.89 + m2 = -3 + 2.89

Reorder the terms:
2.89 + 3.4m + m2 = -3 + 2.89

Combine like terms: -3 + 2.89 = -0.11
2.89 + 3.4m + m2 = -0.11

Factor a perfect square on the left side:
(m + 1.7)(m + 1.7) = -0.11

Can't calculate square root of the right side.

The solution to this equation could not be determined.
