# It's easy, believe me!

Given $$a$$ and $$b$$ are two integers that satisfy

$\large \text{lcm} \left(x^2 + ax - 2, x^2 + 5x + b\right) = x^3 + 4x^2 + x - 6$

Calculate $$a + b$$.

Notation: $$\text{lcm}(\cdots)$$ denotes the lowest common multiple.

This is part of the set: It's easy, believe me!
