Question 436399
It separates because the polynomial can be expressed as a product. We use parentheses so it doesn't look like


x + 3 * x + 2


which is ambiguous (and actually equals x + 3x + 2 by order of operations). To find the roots, we can set both equations to zero, as the entire expression must be 0. Hence, either x+3 = 0 or x+2 = 0, which implies x = -3 or -2.
