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

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

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

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