Question

x ( x + 2 ) + 1 = 0 solve the following equation by factorisation method​

Answer 1

Answer:

x(x+1) + x(x+1) = 0

Step-by-step explanation:

x (x+2) + 1 = 0

(x)^2 +2x +1 = 0

(x)^2 + x + x + 1 = 0

Taking out x as common,

x (x + 1) + 1 (x + 1) = 0

(x + 1) × ( x+ 1) = 0

(x + 1) ^ 2 = 0

now solving for x we get,

x = -1 & x = -1 .
