(2a-1)(a-3)=0

Solution for (2a-1)(a-3)=0 equation:

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

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

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

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

Combine like terms: -1a + -6a = -7a
(3 + -7a + 2a2) = 0

Solving
3 + -7a + 2a2 = 0

Solving for variable 'a'.
