Write a quadratic equation with integer coefficients and roots -2/3 and 1 ž
\n" ); document.write( ":
\n" ); document.write( "Create two factors from the given roots
\n" ); document.write( ":
\n" ); document.write( "x = -2/3
\n" ); document.write( "Multiply both sides by 3
\n" ); document.write( "3x = -2
\n" ); document.write( "(3x + 2) = 0
\n" ); document.write( "and
\n" ); document.write( "x = 1 $\"3%2F4\"$
\n" ); document.write( "x = $\"7%2F4\"$
\n" ); document.write( "multiply both sides by 4
\n" ); document.write( "4x = 7
\n" ); document.write( "(4x - 7) = 0
\n" ); document.write( ":
\n" ); document.write( "FOIL (3x+2)(4x-7)
\n" ); document.write( "12x^2 - 21x + 8x - 14
\n" ); document.write( "combine like terms
\n" ); document.write( "y = 12x^2 - 13x - 14; is the quadratic equation with the given roots
\n" ); document.write( " \n" ); document.write( "

\n" );
