Solution for (x-7)(x-7)=(x^2)+kx+m equation: 


Simplifying
(x + -7)(x + -7) = (x2) + kx + m

Reorder the terms:
(-7 + x)(x + -7) = (x2) + kx + m

Reorder the terms:
(-7 + x)(-7 + x) = (x2) + kx + m

Multiply (-7 + x) * (-7 + x)
(-7(-7 + x) + x(-7 + x)) = (x2) + kx + m
((-7 * -7 + x * -7) + x(-7 + x)) = (x2) + kx + m
((49 + -7x) + x(-7 + x)) = (x2) + kx + m
(49 + -7x + (-7 * x + x * x)) = (x2) + kx + m
(49 + -7x + (-7x + x2)) = (x2) + kx + m

Combine like terms: -7x + -7x = -14x
(49 + -14x + x2) = (x2) + kx + m
49 + -14x + x2 = x2 + kx + m

Reorder the terms:
49 + -14x + x2 = kx + m + x2

Add '-1x2' to each side of the equation.
49 + -14x + x2 + -1x2 = kx + m + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
49 + -14x + 0 = kx + m + x2 + -1x2
49 + -14x = kx + m + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
49 + -14x = kx + m + 0
49 + -14x = kx + m

Solving
49 + -14x = kx + m

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1kx' to each side of the equation.
49 + -1kx + -14x = kx + -1kx + m

Combine like terms: kx + -1kx = 0
49 + -1kx + -14x = 0 + m
49 + -1kx + -14x = m

Add '-49' to each side of the equation.
49 + -1kx + -49 + -14x = -49 + m

Reorder the terms:
49 + -49 + -1kx + -14x = -49 + m

Combine like terms: 49 + -49 = 0
0 + -1kx + -14x = -49 + m
-1kx + -14x = -49 + m

Reorder the terms:
49 + -1kx + -1m + -14x = -49 + m + 49 + -1m

Reorder the terms:
49 + -1kx + -1m + -14x = -49 + 49 + m + -1m

Combine like terms: -49 + 49 = 0
49 + -1kx + -1m + -14x = 0 + m + -1m
49 + -1kx + -1m + -14x = m + -1m

Combine like terms: m + -1m = 0
49 + -1kx + -1m + -14x = 0
