You can put this solution on YOUR website!
-9(x-3)^2=-7 first you must take care of the power term:
\n" ); document.write( "(x-3)^2=x^2-6x+9 now multiply this by -9 thus
\n" ); document.write( "-9(x^2-6x+9)=9x^2+54x-81 now set this term equal to -7 thus:
\n" ); document.write( "9x^2+54x-81=-7 now add 7 from both sides.
\n" ); document.write( "9x^2+54x-81+7=-7+7
\n" ); document.write( "9x^2+54x-72=0 now factor this quadratic equation by dividing each term by 9:
\n" ); document.write( "9(x^2+6x-8)=0 now factor this remaining equation using the quadratic equation:
\n" ); document.write( "\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
\n" ); document.write( "x=(-6+-sqrt[6^2-4*1*-8])/2*1
\n" ); document.write( "x=(-6+-sqrt36+32])/2
\n" ); document.write( "x=(-6+-sqrt68)/2
\n" ); document.write( "x=(-6+-8.246)/2
\n" ); document.write( "x=(-6+8.246)/2
\n" ); document.write( "x=2.246/2
\n" ); document.write( "x=1.123 answer.
\n" ); document.write( "x=(-6-8.246)/2
\n" ); document.write( "x=-14.246)/2
\n" ); document.write( "x=-7.123 answer.
\n" ); document.write( " \n" ); document.write( "
\n" );
