Solve the quadratic equations by factorization method only x² + x + 1 = 0

Accepted Answer

x² + (1 – 2i)x – 2i = 0

Given: x² + (1 – 2i)x – 2i = 0

x² + x – 2ix – 2i = 0

x(x + 1) – 2i(x + 1) = 0

(x + 1) (x – 2i) = 0

x + 1 = 0 or x – 2i = 0

x = –1 or 2i

The roots of the given equation are –1, 2i
