(4x+1)(x-1)=

Solution for (4x+1)(x-1)= equation:

Simplifying
(4x + 1)(x + -1) = 0

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

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

Multiply (1 + 4x) * (-1 + x)
(1(-1 + x) + 4x * (-1 + x)) = 0
((-1 * 1 + x * 1) + 4x * (-1 + x)) = 0
((-1 + 1x) + 4x * (-1 + x)) = 0
(-1 + 1x + (-1 * 4x + x * 4x)) = 0
(-1 + 1x + (-4x + 4x2)) = 0

Combine like terms: 1x + -4x = -3x
(-1 + -3x + 4x2) = 0

Solving
-1 + -3x + 4x2 = 0

Solving for variable 'x'.

Factor a trinomial.
