X ( x + 2 ) + 1 = 0 solve the following equation by factorisation method |
|
Answer» 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 . |
