Given quadrant equation:
3x² + 9x + 6 = 0
Here we see that,
→ Product of coefficient of x² and constant term = 3 × 6 = 18
→ Sum of coefficient of x² ans constant term = 3 + 6 = 9
So the given equation can be written as,
⇛3x² + 6x + 3x + 6 = 0
On taking the common terms, we get
⇛3x(x + 2) + 3(x + 2) = 0
On grouping the common terms, we get
⇛(3x + 3)(x + 2) = 0
Here either (3x + 3) = 0 or (x + 2) = 0. So,
⇛3x + 3 = 0 or x + 2 = 0
⇛3x = -3 or x = -2
⇛x = -3/3 or x = -2
⇛x = -1 or x = -2
