Solution for 2(g+5)=g(g+5)+g^2 equation:


Simplifying
2(g + 5) = g(g + 5) + g2

Reorder the terms:
2(5 + g) = g(g + 5) + g2
(5 * 2 + g * 2) = g(g + 5) + g2
(10 + 2g) = g(g + 5) + g2

Reorder the terms:
10 + 2g = g(5 + g) + g2
10 + 2g = (5 * g + g * g) + g2
10 + 2g = (5g + g2) + g2

Combine like terms: g2 + g2 = 2g2
10 + 2g = 5g + 2g2

Solving
10 + 2g = 5g + 2g2

Solving for variable 'g'.

Combine like terms: 2g + -5g = -3g
10 + -3g + -2g2 = 5g + 2g2 + -5g + -2g2

Reorder the terms:
10 + -3g + -2g2 = 5g + -5g + 2g2 + -2g2

Combine like terms: 5g + -5g = 0
10 + -3g + -2g2 = 0 + 2g2 + -2g2
10 + -3g + -2g2 = 2g2 + -2g2

Combine like terms: 2g2 + -2g2 = 0
10 + -3g + -2g2 = 0

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

Divide each side by '-2'.
-5 + 1.5g + g2 = 0

Move the constant term to the right:

Add '5' to each side of the equation.
-5 + 1.5g + 5 + g2 = 0 + 5

Reorder the terms:
-5 + 5 + 1.5g + g2 = 0 + 5

Combine like terms: -5 + 5 = 0
0 + 1.5g + g2 = 0 + 5
1.5g + g2 = 0 + 5

Combine like terms: 0 + 5 = 5
1.5g + g2 = 5

The g term is 1.5g.  Take half its coefficient (0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
1.5g + 0.5625 + g2 = 5 + 0.5625

Reorder the terms:
0.5625 + 1.5g + g2 = 5 + 0.5625

Combine like terms: 5 + 0.5625 = 5.5625
0.5625 + 1.5g + g2 = 5.5625

Factor a perfect square on the left side:
(g + 0.75)(g + 0.75) = 5.5625

Calculate the square root of the right side: 2.358495283
