x^2-6x+8=0
\n" ); document.write( "x^2-4x-2x+8=0 try to distribute 6 into such 2 parts so that sum =-6 and multiplication = +8
\n" ); document.write( " x(x-4-2(x-4)=0
\n" ); document.write( "(x-4)(x-2)=0
\n" ); document.write( "x=4 or x=2 is the answer to first question \r
\n" ); document.write( "\n" ); document.write( "2)x^2-2x=15
\n" ); document.write( "x^2-5x+3x-15=0
\n" ); document.write( "x(x-5)+3(x-5)=0
\n" ); document.write( "(x-5)(x+3=0
\n" ); document.write( "x=5 or x=-3
\n" ); document.write( " solution to this\r
\n" ); document.write( "\n" ); document.write( "3)x^2-8x+16=0
\n" ); document.write( "x^2-4x-4x+16=0
\n" ); document.write( "x(x-4)-4(x-4)=0
\n" ); document.write( "(x-4)(x-4)=0
\n" ); document.write( "x=4 is uniform answer\r
\n" ); document.write( "\n" ); document.write( "4)x^2+10x+25=0
\n" ); document.write( "x^2+5x+5x+25=0
\n" ); document.write( "x(x+5)+5(x+5)=0
\n" ); document.write( "(x+5)(x+5)=0
\n" ); document.write( "x=-5 uniform soultion\r
