Solve the following equations : (i) 2x^(2)-(3+7i)x-3+9i=0 (ii) (2+i)x^(2)-(5-i)x+2(1-i)=0 (iii) x^(2)-(4+i)x+(5-i)=0 (iv) x^(2)-(5+5i)x+13i=0 (v) x^(2)-(5+2i)x+(9+7i)=0 (vi) x^(2)-(5-i)x+(18+i)=0

Answer»


Solution :(i) ` 3i, (3+i)/(2)`
(ii) `1-i, (4-2i)/(5)`
(iii) `3+2i, 1-i`
(IV) `2+3i, 3+2i`
(V) `3-i, 2+3i`
(vi) ` 3-4i, 2+ 3i`
