(2x-1)(4x+1)=

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

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

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

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

Multiply (-1 + 2x) * (1 + 4x)
(-1(1 + 4x) + 2x * (1 + 4x)) = 0
((1 * -1 + 4x * -1) + 2x * (1 + 4x)) = 0
((-1 + -4x) + 2x * (1 + 4x)) = 0
(-1 + -4x + (1 * 2x + 4x * 2x)) = 0
(-1 + -4x + (2x + 8x2)) = 0

Combine like terms: -4x + 2x = -2x
(-1 + -2x + 8x2) = 0
