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. \"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
\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( "
\n" );
