Algebra.Com's Answer #330834 by Alan3354(69443) You can put this solution on YOUR website! (x^3-7x^2+4x+12); (x-2) use subsitution to tell whether the given binomial is a factor of the polynomial. \n" ); document.write( "----------------- \n" ); document.write( "Sub 2 for x. If f(2)=0, then x-2 is a factor \n" ); document.write( "f(x) = x^3-7x^2+4x+12 \n" ); document.write( "f(2) = 2^3 - 7*2^2 + 4*2 + 12 \n" ); document.write( "= 8 - 28 + 8 + 12 \n" ); document.write( "= 0 \n" ); document.write( "------- \n" ); document.write( "x-2 is a factor. \n" ); document.write( " \n" ); document.write( " |
