Solution for (x-8)(x-k)=x^2-5kx+m equation:


Simplifying
(x + -8)(x + -1k) = x2 + -5kx + m

Reorder the terms:
(-8 + x)(x + -1k) = x2 + -5kx + m

Reorder the terms:
(-8 + x)(-1k + x) = x2 + -5kx + m

Multiply (-8 + x) * (-1k + x)
(-8(-1k + x) + x(-1k + x)) = x2 + -5kx + m
((-1k * -8 + x * -8) + x(-1k + x)) = x2 + -5kx + m
((8k + -8x) + x(-1k + x)) = x2 + -5kx + m
(8k + -8x + (-1k * x + x * x)) = x2 + -5kx + m
(8k + -8x + (-1kx + x2)) = x2 + -5kx + m

Reorder the terms:
(8k + -1kx + -8x + x2) = x2 + -5kx + m
(8k + -1kx + -8x + x2) = x2 + -5kx + m

Reorder the terms:
8k + -1kx + -8x + x2 = -5kx + m + x2

Add '-1x2' to each side of the equation.
8k + -1kx + -8x + x2 + -1x2 = -5kx + m + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
8k + -1kx + -8x + 0 = -5kx + m + x2 + -1x2
8k + -1kx + -8x = -5kx + m + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
8k + -1kx + -8x = -5kx + m + 0
8k + -1kx + -8x = -5kx + m

Solving
8k + -1kx + -8x = -5kx + m

Solving for variable 'k'.

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

Add '5kx' to each side of the equation.
8k + -1kx + 5kx + -8x = -5kx + 5kx + m

Combine like terms: -1kx + 5kx = 4kx
8k + 4kx + -8x = -5kx + 5kx + m

Combine like terms: -5kx + 5kx = 0
8k + 4kx + -8x = 0 + m
8k + 4kx + -8x = m

Add '8x' to each side of the equation.
8k + 4kx + -8x + 8x = m + 8x

Combine like terms: -8x + 8x = 0
8k + 4kx + 0 = m + 8x
8k + 4kx = m + 8x

Reorder the terms:
8k + 4kx + -1m + -8x = m + -1m + 8x + -8x

Combine like terms: m + -1m = 0
8k + 4kx + -1m + -8x = 0 + 8x + -8x
8k + 4kx + -1m + -8x = 8x + -8x

Combine like terms: 8x + -8x = 0
8k + 4kx + -1m + -8x = 0
