Solution for (6w^2-3w+1)-(w^2+w-9)= equation:


Simplifying
(6w2 + -3w + 1) + -1(w2 + w + -9) = 0

Reorder the terms:
(1 + -3w + 6w2) + -1(w2 + w + -9) = 0

Remove parenthesis around (1 + -3w + 6w2)
1 + -3w + 6w2 + -1(w2 + w + -9) = 0

Reorder the terms:
1 + -3w + 6w2 + -1(-9 + w + w2) = 0
1 + -3w + 6w2 + (-9 * -1 + w * -1 + w2 * -1) = 0
1 + -3w + 6w2 + (9 + -1w + -1w2) = 0

Reorder the terms:
1 + 9 + -3w + -1w + 6w2 + -1w2 = 0

Combine like terms: 1 + 9 = 10
10 + -3w + -1w + 6w2 + -1w2 = 0

Combine like terms: -3w + -1w = -4w
10 + -4w + 6w2 + -1w2 = 0

Combine like terms: 6w2 + -1w2 = 5w2
10 + -4w + 5w2 = 0

Solving
10 + -4w + 5w2 = 0

Solving for variable 'w'.

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

Divide each side by '5'.
2 + -0.8w + w2 = 0

Move the constant term to the right:

Add '-2' to each side of the equation.
2 + -0.8w + -2 + w2 = 0 + -2

Reorder the terms:
2 + -2 + -0.8w + w2 = 0 + -2

Combine like terms: 2 + -2 = 0
0 + -0.8w + w2 = 0 + -2
-0.8w + w2 = 0 + -2

Combine like terms: 0 + -2 = -2
-0.8w + w2 = -2

The w term is -0.8w.  Take half its coefficient (-0.4).
Square it (0.16) and add it to both sides.

Add '0.16' to each side of the equation.
-0.8w + 0.16 + w2 = -2 + 0.16

Reorder the terms:
0.16 + -0.8w + w2 = -2 + 0.16

Combine like terms: -2 + 0.16 = -1.84
0.16 + -0.8w + w2 = -1.84

Factor a perfect square on the left side:
(w + -0.4)(w + -0.4) = -1.84

Can't calculate square root of the right side.

The solution to this equation could not be determined.
