anyone know how to solve?

solve step by step

12a^2b - 4ab + 8b = 4b(3a^2 - a + 2)

12a^2b - 4ab + 8b = 4b(3a^2 - a + 2)
Simplifying 12a2b + -4ab + 8b = 4b(3a2 + -1a + 2)
Reorder the terms: -4ab + 12a2b + 8b = 4b(3a2 + -1a + 2)
Reorder the terms: -4ab + 12a2b + 8b = 4b(2 + -1a + 3a2) -4ab + 12a2b + 8b = (2 * 4b + -1a * 4b + 3a2 * 4b)
Reorder the terms: -4ab + 12a2b + 8b = (-4ab + 12a2b + 8b) -4ab + 12a2b + 8b = (-4ab + 12a2b + 8b)
Add '4ab' to each side of the equation. -4ab + 12a2b + 4ab + 8b = -4ab + 12a2b + 4ab + 8b
Reorder the terms: -4ab + 4ab + 12a2b + 8b = -4ab + 12a2b + 4ab + 8b Combine like terms: -4ab + 4ab = 0 0 + 12a2b + 8b = -4ab + 12a2b + 4ab + 8b 12a2b + 8b = -4ab + 12a2b + 4ab + 8b Reorder the terms: 12a2b + 8b = -4ab + 4ab + 12a2b + 8b
Combine like terms: -4ab + 4ab = 0 12a2b + 8b = 0 + 12a2b + 8b 12a2b + 8b = 12a2b + 8b Add '-12a2b' to each side of the equation. 12a2b + -12a2b + 8b = 12a2b + -12a2b + 8b
Combine like terms: 12a2b + -12a2b = 0 0 + 8b = 12a2b + -12a2b + 8b 8b = 12a2b + -12a2b + 8b
Combine like terms: 12a2b + -12a2b = 0 8b = 0 + 8b 8b = 8b
Add '-8b' to each side of the equation. 8b + -8b = 8b + -8b

Combine like terms: 8b + -8b = 0 0 = 8b + -8b
Combine like terms: 8b + -8b = 0 0 = 0
Solving 0 = 0
