Question

( 2 x^{2}+3 i x+2=0 )
( x Leftrightarrow x=+31 pm sqrt{(3 i)^{2}-4(2)(2) / 4} )
( quad=-3 i pm sqrt{9 i^{2}-16} / 4 quad i=-1 )
( quad=-3 i pm 5 i )
( x^{2}+7 i n-12=0 )
( x=-(-7 i) pm sqrt{(7 i)^{2}-4(1)(-12) / 2} )
( =7 i pm sqrt{49 i^{2}+48 / 2} )
( =frac{7 i pm 1}{2} )

# Solve the following by factorization. (0) 2x + 3ix + 2 = 0 (il) X- 7ix - 12 = 0

Solution
