I'm supposed to solve for the roots of each quadratic equation by using the factoring method. This is so confusing to me it's almost painful. I honestly don't know where to start.
\n" ); document.write( "X^2+3x-40=0 is the problem. If you could get this to make sense to me I would greatly appreciate it.\r
\n" ); document.write( "\n" ); document.write( " Factor:
\n" ); document.write( "x^2+3x-40=0\r
\n" ); document.write( "\n" ); document.write( "This quadratic is in the form ax^2+bx+c=0
\n" ); document.write( "where: a=1
\n" ); document.write( " b=3
\n" ); document.write( " c=-40\r
\n" ); document.write( "\n" ); document.write( "When a=1, then, if it is factorable, the sum of the products of c must equal b \r
\n" ); document.write( "\n" ); document.write( "what are the products of -40 that equals +3, are they:
\n" ); document.write( "-10 time +4 ------------no
\n" ); document.write( "-2 times +20--------------no
\n" ); document.write( "-40 times +1---------------no
\n" ); document.write( "-8 times +5-----------no
\n" ); document.write( "+8 times -5-------------BINGO!!!!!!!!!!!!!!!\r
\n" ); document.write( "\n" ); document.write( "Soooo(x+8)(x-5)=0 (Multiplying it out: x^2-5x+8x-40=x^2+3x-40)
\n" ); document.write( "x+8=0
\n" ); document.write( "x=-8 and
\n" ); document.write( "x-5=0
\n" ); document.write( "x=+5\r
\n" ); document.write( "
