k=(5u+1)(2-3u)

Solution for k=(5u+1)(2-3u) equation:

Simplifying
k = (5u + 1)(2 + -3u)

Reorder the terms:
k = (1 + 5u)(2 + -3u)

Multiply (1 + 5u) * (2 + -3u)
k = (1(2 + -3u) + 5u * (2 + -3u))
k = ((2 * 1 + -3u * 1) + 5u * (2 + -3u))
k = ((2 + -3u) + 5u * (2 + -3u))
k = (2 + -3u + (2 * 5u + -3u * 5u))
k = (2 + -3u + (10u + -15u2))

Combine like terms: -3u + 10u = 7u
k = (2 + 7u + -15u2)

Solving
k = 2 + 7u + -15u2

Solving for variable 'k'.

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

Simplifying
