Question

अवयव पाडा: 3x² + 14x + 15

Answer 1

Answer:

Step-by-step explanation:

3x²+14x+15 = 0

3x²+9x+5x+15 = 0

3x(x+3)+5(x+3) = 0

(3x+5) (x+3) = 0

3x+5 = 0 OR x+3 = 0

x = -5/3 OR x = -3

Answer 2

3x^2
$3x { }^{2} + 14x + 15 \\ = 3 {x}^{2} + 9x +5x + 15 \\ = 3x(x + 9) + 5(x + 9) \\ = (3x + 5) + (x + 9)$
hope it help you
