Solution for (5m-6)(5m-6)=7 equation:


Simplifying
(5m + -6)(5m + -6) = 7

Reorder the terms:
(-6 + 5m)(5m + -6) = 7

Reorder the terms:
(-6 + 5m)(-6 + 5m) = 7

Multiply (-6 + 5m) * (-6 + 5m)
(-6(-6 + 5m) + 5m * (-6 + 5m)) = 7
((-6 * -6 + 5m * -6) + 5m * (-6 + 5m)) = 7
((36 + -30m) + 5m * (-6 + 5m)) = 7
(36 + -30m + (-6 * 5m + 5m * 5m)) = 7
(36 + -30m + (-30m + 25m2)) = 7

Combine like terms: -30m + -30m = -60m
(36 + -60m + 25m2) = 7

Solving
36 + -60m + 25m2 = 7

Solving for variable 'm'.

Reorder the terms:
36 + -7 + -60m + 25m2 = 7 + -7

Combine like terms: 36 + -7 = 29
29 + -60m + 25m2 = 7 + -7

Combine like terms: 7 + -7 = 0
29 + -60m + 25m2 = 0

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

Divide each side by '25'.
1.16 + -2.4m + m2 = 0

Move the constant term to the right:

Add '-1.16' to each side of the equation.
1.16 + -2.4m + -1.16 + m2 = 0 + -1.16

Reorder the terms:
1.16 + -1.16 + -2.4m + m2 = 0 + -1.16

Combine like terms: 1.16 + -1.16 = 0.00
0.00 + -2.4m + m2 = 0 + -1.16
-2.4m + m2 = 0 + -1.16

Combine like terms: 0 + -1.16 = -1.16
-2.4m + m2 = -1.16

The m term is -2.4m.  Take half its coefficient (-1.2).
Square it (1.44) and add it to both sides.

Add '1.44' to each side of the equation.
-2.4m + 1.44 + m2 = -1.16 + 1.44

Reorder the terms:
1.44 + -2.4m + m2 = -1.16 + 1.44

Combine like terms: -1.16 + 1.44 = 0.28
1.44 + -2.4m + m2 = 0.28

Factor a perfect square on the left side:
(m + -1.2)(m + -1.2) = 0.28

Calculate the square root of the right side: 0.529150262

Break this problem into two subproblems by setting 
(m + -1.2) equal to 0.529150262 and -0.529150262.

Subproblem 1

m + -1.2 = 0.529150262 Simplifying m + -1.2 = 0.529150262 Reorder the terms: -1.2 + m = 0.529150262 Solving -1.2 + m = 0.529150262 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '1.2' to each side of the equation. -1.2 + 1.2 + m = 0.529150262 + 1.2 Combine like terms: -1.2 + 1.2 = 0.0 0.0 + m = 0.529150262 + 1.2 m = 0.529150262 + 1.2 Combine like terms: 0.529150262 + 1.2 = 1.729150262 m = 1.729150262 Simplifying m = 1.729150262

Subproblem 2

m + -1.2 = -0.529150262 Simplifying m + -1.2 = -0.529150262 Reorder the terms: -1.2 + m = -0.529150262 Solving -1.2 + m = -0.529150262 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '1.2' to each side of the equation. -1.2 + 1.2 + m = -0.529150262 + 1.2 Combine like terms: -1.2 + 1.2 = 0.0 0.0 + m = -0.529150262 + 1.2 m = -0.529150262 + 1.2 Combine like terms: -0.529150262 + 1.2 = 0.670849738 m = 0.670849738 Simplifying m = 0.670849738
