Algebra.Com's Answer #209359 by alegriajoy33(14)![]() ![]() You can put this solution on YOUR website! First step. \n" ); document.write( "Multiply the entire equation by (y-1)(2y-2) \n" ); document.write( "so you get 3(y-1)-2(2y-2)= -1/2(y-1)(2y-2) \n" ); document.write( "second step. \n" ); document.write( "simplify. \n" ); document.write( "first foil the (y-1)(2y-2) = (2y^2)-4y-2 \n" ); document.write( "then you distribute the 3 the -2 and the -1/2 \n" ); document.write( "you get 3y-3-4y+4= (-y^2)+2y+1 \n" ); document.write( "now combine like terms \n" ); document.write( "you get -y+1=(-y^2)+2y+1 \n" ); document.write( "now add y \n" ); document.write( "you get 1=(-y^2)+2y+1 \n" ); document.write( "subtract 1 \n" ); document.write( "you get 0=(-y^2)+2y+0 \n" ); document.write( "now you can either use quadratic formula or foil \n" ); document.write( "this is the quadratic formula. \n" ); document.write( "A is -1, B is 2, and C is 0 just plug in and solve. \n" ); document.write( "this equation cannot be factored but after plugging in the numbers in the formula you shoud get the answers well youll get x = but it same as y= in this case. answer is y=0 and y=2 make sure to check your answers by plugging the final answers into the origional equation and in this case I did and found out that 2 is the only solution for 0 does not work. \n" ); document.write( " |
