Solution for (a+b)x^2+(a+b)x-3a(a+b)= equation: 


Simplifying
(a + b) * x2 + (a + b) * x + -3a(a + b) = 0

Reorder the terms for easier multiplication:
x2(a + b) + (a + b) * x + -3a(a + b) = 0
(a * x2 + b * x2) + (a + b) * x + -3a(a + b) = 0
(ax2 + bx2) + (a + b) * x + -3a(a + b) = 0

Reorder the terms for easier multiplication:
ax2 + bx2 + x(a + b) + -3a(a + b) = 0
ax2 + bx2 + (a * x + b * x) + -3a(a + b) = 0
ax2 + bx2 + (ax + bx) + -3a(a + b) = 0
ax2 + bx2 + ax + bx + (a * -3a + b * -3a) = 0

Reorder the terms:
ax2 + bx2 + ax + bx + (-3ab + -3a2) = 0
ax2 + bx2 + ax + bx + (-3ab + -3a2) = 0

Reorder the terms:
-3ab + ax + ax2 + -3a2 + bx + bx2 = 0

Solving
-3ab + ax + ax2 + -3a2 + bx + bx2 = 0

Solving for variable 'a'.
