How do you find a quadratic equation if you are only given the solution
\n" ); document.write( ".
\n" ); document.write( "Let's say, for example, you were given that the solutions of a quadratic is:
\n" ); document.write( "x = {-3, 6}
\n" ); document.write( ".
\n" ); document.write( "Given that, you can say that the following are factors:
\n" ); document.write( "(x+3)
\n" ); document.write( "and
\n" ); document.write( "(x-6)
\n" ); document.write( "That is, if you saw:
\n" ); document.write( "(x+3)(x-6) = 0
\n" ); document.write( "you would say the solutions are x = {-3, 6}
\n" ); document.write( ".
\n" ); document.write( "To find the quadratic, multiply the two factors:
\n" ); document.write( "(x+3)(x-6)
\n" ); document.write( "Applying FOIL:
\n" ); document.write( "x^2 - 6x + 3x - 18
\n" ); document.write( "x^2 - 3x - 18 (This would be your quadratic)\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
