Algebra.Com's Answer #133048 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! If two roots of a quadratic is: \n" ); document.write( "-3/4, -2/3 \n" ); document.write( "then the quadratic must have the following factors: \n" ); document.write( "(x+3/4), (x+2/3) \n" ); document.write( ". \n" ); document.write( "To get our quadratic, we multiply the two factors together using FOIL: \n" ); document.write( "(x+3/4)(x+2/3) \n" ); document.write( "x^2 + 2/3 x + 3/4 x +6/12 \n" ); document.write( "x^2 + 8/12 x + 9/12 x + 1/2 \n" ); document.write( "x^2 + 17/12 x + 1/2 \n" ); document.write( "x^2 + 17x/12 + 1/2 (this is what they're looking for)\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
