Question

Solve by Factorisation X2+5x+6=0.​

Answer 1

Answer:

(X+3)(X+2)

X=-3 or-2

Step-by-step explanation:

x²+3x+2x+6=0

X(X+3)+2(X+3)=0

(X+3)(X+2)=0

X=-3 or-2

Answer 2

Step-by-step explanation:

x^2+5x+6

x^2+2x+3x+6

X(X+2) + 3(X+2)

(X+2)(X+3)

equating (X+2) and (X+3) with zero

1). X+2=0. 2). X+3=0

X= -2. X= -3

putting the value of X = -2 and -3 in x^2+5x+6

X= -2. X= -3

x^2+5x+6. x^2+5x+6=0

(-2)^2 + 5*-2 +6=0. (-3)^2+5*-3+6=0

4 -10+6 =0 9-10+6=0

-6+6=0 =0 -6+6=0

0=0 0=0

checked. checked
