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

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

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

Reorder the terms:
A = 3a(-1 + a) + -2(1 + -1a)
A = (-1 * 3a + a * 3a) + -2(1 + -1a)
A = (-3a + 3a2) + -2(1 + -1a)
A = -3a + 3a2 + (1 * -2 + -1a * -2)
A = -3a + 3a2 + (-2 + 2a)

Reorder the terms:
A = -2 + -3a + 2a + 3a2
