determine whether the following equations have solutions that are two different rational solutions:two different irrational solutions:exactly one rational solution or two different imaginary solutions.
\n" ); document.write( "3 + 8z^2= -7z
\n" ); document.write( "---
\n" ); document.write( "Rearrange:
\n" ); document.write( "8z^2+7z+3 = 0
\n" ); document.write( "a=8 ; b=7 ; c=3
\n" ); document.write( "-------------------
\n" ); document.write( "Discriminant = b^2-4ac = 49 -4*8*3 < 0
\n" ); document.write( "---
\n" ); document.write( "Since the discriminant is < 0
\n" ); document.write( "the quadrated has two different imaginary solutions.
