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

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

Simplifying
(2k + 3)(k + -1) = 0

Reorder the terms:
(3 + 2k)(k + -1) = 0

Reorder the terms:
(3 + 2k)(-1 + k) = 0

Multiply (3 + 2k) * (-1 + k)
(3(-1 + k) + 2k * (-1 + k)) = 0
((-1 * 3 + k * 3) + 2k * (-1 + k)) = 0
((-3 + 3k) + 2k * (-1 + k)) = 0
(-3 + 3k + (-1 * 2k + k * 2k)) = 0
(-3 + 3k + (-2k + 2k2)) = 0

Combine like terms: 3k + -2k = 1k
(-3 + 1k + 2k2) = 0

Solving
-3 + 1k + 2k2 = 0

Solving for variable 'k'.

Factor a trinomial.
