(x + 4)^2 = 15 - 2x^2
\n" ); document.write( "x^2 + 8x + 16 = 15 - 2x^2
\n" ); document.write( "3x^2 + 8x + 1 = 0
\n" ); document.write( "Using
\n" ); document.write( "\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
\n" ); document.write( "\"x+=+%28-8+%2B-+sqrt%28+8%5E2-4%2A3%2A1%29%29%2F%282%2A3%29+\"
\n" ); document.write( "\"x+=+%28-8+%2B-+sqrt%28+52+%29%29%2F%286%29+\"
\n" ); document.write( " x = -8 +- 7.2/6
\n" ); document.write( " x = -15.2/6 or x = -0.8/6
\n" ); document.write( " x = -2.53 or x = -0.13
