(a+1)(a+2)=y

Solution for (a+1)(a+2)=y equation:

Simplifying
(a + 1)(a + 2) = y

Reorder the terms:
(1 + a)(a + 2) = y

Reorder the terms:
(1 + a)(2 + a) = y

Multiply (1 + a) * (2 + a)
(1(2 + a) + a(2 + a)) = y
((2 * 1 + a * 1) + a(2 + a)) = y
((2 + 1a) + a(2 + a)) = y
(2 + 1a + (2 * a + a * a)) = y
(2 + 1a + (2a + a2)) = y

Combine like terms: 1a + 2a = 3a
(2 + 3a + a2) = y

Solving
2 + 3a + a2 = y

Solving for variable 'a'.

Combine like terms: y + -1y = 0
2 + 3a + a2 + -1y = 0
