Solution for m(3-4m)=7 equation:


Simplifying
m(3 + -4m) = 7
(3 * m + -4m * m) = 7
(3m + -4m2) = 7

Solving
3m + -4m2 = 7

Solving for variable 'm'.

Reorder the terms:
-7 + 3m + -4m2 = 7 + -7

Combine like terms: 7 + -7 = 0
-7 + 3m + -4m2 = 0

Begin completing the square.  Divide all terms by
-4 the coefficient of the squared term: 

Divide each side by '-4'.
1.75 + -0.75m + m2 = 0

Move the constant term to the right:

Add '-1.75' to each side of the equation.
1.75 + -0.75m + -1.75 + m2 = 0 + -1.75

Reorder the terms:
1.75 + -1.75 + -0.75m + m2 = 0 + -1.75

Combine like terms: 1.75 + -1.75 = 0.00
0.00 + -0.75m + m2 = 0 + -1.75
-0.75m + m2 = 0 + -1.75

Combine like terms: 0 + -1.75 = -1.75
-0.75m + m2 = -1.75

The m term is -0.75m.  Take half its coefficient (-0.375).
Square it (0.140625) and add it to both sides.

Add '0.140625' to each side of the equation.
-0.75m + 0.140625 + m2 = -1.75 + 0.140625

Reorder the terms:
0.140625 + -0.75m + m2 = -1.75 + 0.140625

Combine like terms: -1.75 + 0.140625 = -1.609375
0.140625 + -0.75m + m2 = -1.609375

Factor a perfect square on the left side:
(m + -0.375)(m + -0.375) = -1.609375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
