Solution for 2w^2+7w+7-w^2-10w+25=0 equation:


Simplifying
2w2 + 7w + 7 + -1w2 + -10w + 25 = 0

Reorder the terms:
7 + 25 + 7w + -10w + 2w2 + -1w2 = 0

Combine like terms: 7 + 25 = 32
32 + 7w + -10w + 2w2 + -1w2 = 0

Combine like terms: 7w + -10w = -3w
32 + -3w + 2w2 + -1w2 = 0

Combine like terms: 2w2 + -1w2 = 1w2
32 + -3w + 1w2 = 0

Solving
32 + -3w + 1w2 = 0

Solving for variable 'w'.

Begin completing the square.

Move the constant term to the right:

Add '-32' to each side of the equation.
32 + -3w + -32 + w2 = 0 + -32

Reorder the terms:
32 + -32 + -3w + w2 = 0 + -32

Combine like terms: 32 + -32 = 0
0 + -3w + w2 = 0 + -32
-3w + w2 = 0 + -32

Combine like terms: 0 + -32 = -32
-3w + w2 = -32

The w term is -3w.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3w + 2.25 + w2 = -32 + 2.25

Reorder the terms:
2.25 + -3w + w2 = -32 + 2.25

Combine like terms: -32 + 2.25 = -29.75
2.25 + -3w + w2 = -29.75

Factor a perfect square on the left side:
(w + -1.5)(w + -1.5) = -29.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
