Solution for A(t-3)(t-9)=0 equation:


Simplifying
A(t + -3)(t + -9) = 0

Reorder the terms:
A(-3 + t)(t + -9) = 0

Reorder the terms:
A(-3 + t)(-9 + t) = 0

Multiply (-3 + t) * (-9 + t)
A(-3(-9 + t) + t(-9 + t)) = 0
A((-9 * -3 + t * -3) + t(-9 + t)) = 0
A((27 + -3t) + t(-9 + t)) = 0
A(27 + -3t + (-9 * t + t * t)) = 0
A(27 + -3t + (-9t + t2)) = 0

Combine like terms: -3t + -9t = -12t
A(27 + -12t + t2) = 0
(27 * A + -12t * A + t2 * A) = 0
(27A + -12tA + t2A) = 0

Solving
27A + -12tA + t2A = 0

Solving for variable 'A'.

Move all terms containing A to the left, all other terms to the right.
