Expert Answer:

(x2 + x - 2)(x2 +x - 3) = 12
put x+ x = m
and solving it you will get m = 6 or m = -1
Hence, 
x+ x = 6 or x+ x = -1
x+ x - 6 = 0 or x+ x + 1 = 0 
x = -3 or x = 2 or x+ x + 1 = 0
x+ x + 1 = 0 this equation has non-real roots find it using formula and then find sum of two non-real roots.
