1.	If -i + 2 is one root of the equation ax2 – bx + c = 0, then the other root is (a) – i – 2 (b) i – 2 (c) 2 + i(d) 2i + i
Answer» (c) 2 + i Complex roots occur in pairs when -i + 2 is one root, i.e., when 2 – i is a root, the other root is 2 + i

If -i + 2 is one root of the equation ax2 – bx + c = 0, then the other root is (a) – i – 2 (b) i – 2 (c) 2 + i(d) 2i + i

Answer»

(c) 2 + i

Complex roots occur in pairs when -i + 2 is one root, i.e., when 2 – i is a root, the other root is 2 + i
