You can put this solution on YOUR website!
Since I do not have any information on the grade level you are in, I will assume that you wrote the problem correctly, although the answer for the problem that you entered will have an imaginary answer:\r
\n" ); document.write( "\n" ); document.write( "You stated the problem as being x^2 = 2x – 5.
\n" ); document.write( "If that is correct, we set the equation to zero by adding –(2x-5) to both sides, or, maybe more simply, by adding (-2x) and adding 5 to both sides.
\n" ); document.write( "This gives you x^2 – 2x + 5 = 0.
\n" ); document.write( "We now must use the quadratic formula.
\n" ); document.write( "X=[ -b ± sqrt (b^2 – 4ac)] / 2a where a = 1, b = -2, and c = 5 from our equation.
\n" ); document.write( "This gives us:
\n" ); document.write( "X = [+2 ± sqrt (4 – 4(1)(5)] / 2
\n" ); document.write( "Which gives us….
\n" ); document.write( "X = [2 ± sqrt (-16)] / 2
\n" ); document.write( "Which gives us….
\n" ); document.write( "X = [2 ± 4i] / 2
\n" ); document.write( "Which gives us…
\n" ); document.write( "X = 1 ± 2i.\r
\n" ); document.write( "\n" ); document.write( "If you are not working with imaginary numbers yet, check the signs of the problem that you submitted. If the 5 is positive, then that would eliminate the imaginary answer.
\n" ); document.write( "Good luck.
\n" ); document.write( " \n" ); document.write( "
