Question

x^2+6x+9 factorise it.
​

Answer 1

Answer:

Step-by-step explanation:

We Have :-

$x^{2} + 6x + 9$

We have to factorise it

$x^{2} + 6x + 9 = 0\\\\x^{2} + 3x + 3x + 9 = 0\\\\x ( x + 3 ) + 3 ( x + 3 ) = 0\\\\( x + 3 ) ( x + 3 ) = 0\\\\x = -3 , -3$

Answer 2

Answer:

$= > {x}^{2} + 6x + 9 \\ \\ = > {x}^{2} + (3 + 3)x + 9 \\ \\ = > {x }^{2} + 3x + 3x + 9 \\ \\ = > x(x + 3) + 3(x + 3) \\ \\ = > (x + 3)(x + 3) \\ \\ = > {(x + 3)}^{2}$
