Algebra.Com's Answer #655747 by Boreal(15235) You can put this solution on YOUR website! The factors would be (x-1)(4x+1)(2x-3). Set each of those equal to zero, and the roots 1, -1/4, and 3/2 would occur. \n" ); document.write( "Foil the second and third and get (8x^2-10x-3). Multiply that by (x-1) for 8x^3-8x^2-10x^2+10x-3x+3 \n" ); document.write( "The polynomial is 8x^3-18x^2+7x+3. \n" ); document.write( " |
