8x-2 = x^2+15x
\n" ); document.write( "x^2 +7x = -2
\n" ); document.write( "complete the square
\n" ); document.write( "x^2 +7x + 49/4 = -8/4 + 49/4
\n" ); document.write( "(x + 7/2)^2 = 41/4
\n" ); document.write( "x + 7/2 = square root(41/4)
\n" ); document.write( "x + 7/2 = + or - 3.20
\n" ); document.write( "x = -3.50 + 3.20 = -0.30
\n" ); document.write( "x = -3.50 - 3.20 = -6.70
\n" ); document.write( "x = -0.30 or -6.70\r
