\"Solve.
\n" ); document.write( " $\"v%5E2-7v-30=0\"$
\n" ); document.write( "The solution is v=_____.
\n" ); document.write( "(Use a comma to separate answers as needed.)
\n" ); document.write( "ANSWER I GOT: 10, -3
\n" ); document.write( "AM I RIGHT??\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if answers are 10 and -3 then those would need to be the zeroes of that quadratic equation, and the following must be true:
\n" ); document.write( "(v - 10)(v + 3) = 0, v = 10 and v = -3 (10 - 10 = 0, -3 + 3 = 0)
\n" ); document.write( "v^2 + 3v - 10v - 30 = 0, used FOIL (First Outer Inner Last)
\n" ); document.write( "v^2 - 7v - 30 = 0, same as above, so yes
\n" ); document.write( " \n" ); document.write( "

\n" );
