Solution for (4k-1)(k+2)= equation:


Simplifying
(4k + -1)(k + 2) = 0

Reorder the terms:
(-1 + 4k)(k + 2) = 0

Reorder the terms:
(-1 + 4k)(2 + k) = 0

Multiply (-1 + 4k) * (2 + k)
(-1(2 + k) + 4k * (2 + k)) = 0
((2 * -1 + k * -1) + 4k * (2 + k)) = 0
((-2 + -1k) + 4k * (2 + k)) = 0
(-2 + -1k + (2 * 4k + k * 4k)) = 0
(-2 + -1k + (8k + 4k2)) = 0

Combine like terms: -1k + 8k = 7k
(-2 + 7k + 4k2) = 0

Solving
-2 + 7k + 4k2 = 0
