Algebra.Com's Answer #43944 by Nate(3500)![]() ![]() ![]() You can put this solution on YOUR website! Roots are when the graphed line crosses the x-axis as to say.... \n" ); document.write( "Example: \n" ); document.write( "(x - 4)(x + 9)(x - 3) = f(x) \n" ); document.write( "When f(x) = 0, you have defined roots for the x-terms.... \n" ); document.write( "x = 4 because (x - 4) = (4 - 4) = 0 = f(x) \n" ); document.write( "x = -9 \n" ); document.write( "x = 3 \n" ); document.write( "Are all roots.... \n" ); document.write( "Now ~> \n" ); document.write( "if i have the roots 3,-1,2 \n" ); document.write( "(x - 3)(x + 1)(x - 2) = f(x) \n" ); document.write( "(x^2 - 2x - 3)(x - 2) = f(x) \n" ); document.write( "x^3 - 2x^2 - 3x - 2x^2 + 4x + 6 = f(x) \n" ); document.write( "x^3 - 4x^2 + x + 6 = f(x) \n" ); document.write( " |
