Solution for (w-5)(w-5)+54=0 equation:


Simplifying
(w + -5)(w + -5) + 54 = 0

Reorder the terms:
(-5 + w)(w + -5) + 54 = 0

Reorder the terms:
(-5 + w)(-5 + w) + 54 = 0

Multiply (-5 + w) * (-5 + w)
(-5(-5 + w) + w(-5 + w)) + 54 = 0
((-5 * -5 + w * -5) + w(-5 + w)) + 54 = 0
((25 + -5w) + w(-5 + w)) + 54 = 0
(25 + -5w + (-5 * w + w * w)) + 54 = 0
(25 + -5w + (-5w + w2)) + 54 = 0

Combine like terms: -5w + -5w = -10w
(25 + -10w + w2) + 54 = 0

Reorder the terms:
25 + 54 + -10w + w2 = 0

Combine like terms: 25 + 54 = 79
79 + -10w + w2 = 0

Solving
79 + -10w + w2 = 0

Solving for variable 'w'.

Begin completing the square.

Move the constant term to the right:

Add '-79' to each side of the equation.
79 + -10w + -79 + w2 = 0 + -79

Reorder the terms:
79 + -79 + -10w + w2 = 0 + -79

Combine like terms: 79 + -79 = 0
0 + -10w + w2 = 0 + -79
-10w + w2 = 0 + -79

Combine like terms: 0 + -79 = -79
-10w + w2 = -79

The w term is -10w.  Take half its coefficient (-5).
Square it (25) and add it to both sides.

Add '25' to each side of the equation.
-10w + 25 + w2 = -79 + 25

Reorder the terms:
25 + -10w + w2 = -79 + 25

Combine like terms: -79 + 25 = -54
25 + -10w + w2 = -54

Factor a perfect square on the left side:
(w + -5)(w + -5) = -54

Can't calculate square root of the right side.
