Could you please help solve this quadratic equation using completing the square method?
\n" ); document.write( "x^2+9x+8=0
\n" ); document.write( "complete the square: (take 1/2 the coefficient of the x-term(9/2) and square it)
\n" ); document.write( "(x^2+9x+81/4)-81/4+8=0
\n" ); document.write( "(x+9/2)^2=81/4-32/4=49/4
\n" ); document.write( "(x+9/2)^2=49/4
\n" ); document.write( "take sqrt of both sides
\n" ); document.write( "x+9/2=±√(49/4)
\n" ); document.write( "x=-9/2±7/2
\n" ); document.write( "x=-16/2=-8
\n" ); document.write( "or
\n" ); document.write( "x=-2/2=-1
\n" ); document.write( "
