x^2 + x - ( ᴀ + 1 ) ( ᴀ + 2 ) = 0
ᴏʀ , x^2 + { ( ᴀ + 2 ) - ( ᴀ + 1 ) } x - ( ᴀ + 1 ) ( ᴀ + 2 ) = 0
ᴏʀ , x^2 + ( ᴀ + 2 ) x - ( ᴀ + 1 ) x - ( ᴀ + 1 ) ( ᴀ + 2 ) = 0
ᴏʀ , x ( x + ᴀ + 2 ) - ( ᴀ + 1 ) ( x + ᴀ + 2 ) = 0
ᴏʀ , ( x + ᴀ + 2 ) ( x - ᴀ - 1 ) = 0
ɴᴏᴡ , ɴɪᴛʜᴇʀ ,
( x + ᴀ + 2 ) = 0 ( x - ᴀ - 1 ) = 0
ᴏʀ , x = - ᴀ - 2 ᴏʀ , x = ᴀ + 1
ᴏʀ , x = - ( ᴀ + 2 ). ᴏʀ , x = ( ᴀ + 1 )
