Question

factorise X2+5X+6 fast
​

Answer 1

Step-by-step explanation:

Hence x^2+5x+6=(x+2)(x+3).

Hence x^2+5x+6=(x+2)(x+3). Now if this equation is equal to zero then x=-2 and x=-3 which are the factors.

Therefore, the two factors are (x+3) and (x+2)

Answer 2

Answer:

We have,

$\longmapsto {x}^{2} + 5x + 6$

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

$= {x}^{2} + 2x + 3x + 6$

$= x(x) + x(2) + 3(x) + 3(2)$

$= x(x + 2) + 3(x + 2)$

$= (x + 2)(x + 3)$
