(2a+1)(4a-3)=

Solution for (2a+1)(4a-3)= equation:

Simplifying
(2a + 1)(4a + -3) = 0

Reorder the terms:
(1 + 2a)(4a + -3) = 0

Reorder the terms:
(1 + 2a)(-3 + 4a) = 0

Multiply (1 + 2a) * (-3 + 4a)
(1(-3 + 4a) + 2a * (-3 + 4a)) = 0
((-3 * 1 + 4a * 1) + 2a * (-3 + 4a)) = 0
((-3 + 4a) + 2a * (-3 + 4a)) = 0
(-3 + 4a + (-3 * 2a + 4a * 2a)) = 0
(-3 + 4a + (-6a + 8a2)) = 0

Combine like terms: 4a + -6a = -2a
(-3 + -2a + 8a2) = 0

Solving
-3 + -2a + 8a2 = 0
