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

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

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

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

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

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

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

Solving
-3 + 2a + 8a2 = 0
