You can put this solution on YOUR website!
You're supposed to find the roots of the equations. Since the
\n" ); document.write( "largest exponent is 2 (x^2), there are 2 roots in each case.
\n" ); document.write( "The roots are values for the unknown that make the equation 0.
\n" ); document.write( "Say the roots are r1 and r2, then
\n" ); document.write( "(x - r1)(x - r2) = 0
\n" ); document.write( "If you then make x = r1,
\n" ); document.write( "(r1 - r1)(r1 - r2) = 0 this is true
\n" ); document.write( "If you make x = r2, then
\n" ); document.write( "(r2 - r1)(r2 - r2) = 0 this is true also
\n" ); document.write( "How do you find the roots? Use the so-called quadratic formula
\n" ); document.write( "\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
\n" ); document.write( "a = 14
\n" ); document.write( "b = -20
\n" ); document.write( "c = +6
\n" ); document.write( "\"x+=+%28-%28-20%29+%2B-+sqrt%28+%28-20%29%5E2-4%2A14%2A6+%29%29%2F%282%2A14%29+\"
\n" ); document.write( "\"x+=+%2820+%2B-+sqrt%28400+-+336%29%29%2F28+\"
\n" ); document.write( "\"x+=+%2820+%2B-+sqrt%2864%29%29%2F28+\"
\n" ); document.write( "\"x+=+%2820+%2B+8%29+%2F+28\"
\n" ); document.write( "and
\n" ); document.write( "\"x+=+%2820+-+8%29+%2F+28\"
\n" ); document.write( "or, \"x+=+1\" and \"x+=+3%2F7\"
\n" ); document.write( "So, your factors are
\n" ); document.write( "\"%28x+-+1%29%28x+-+%283%2F7%29%29\"
\n" ); document.write( "Do these multiplied together give you the original equation?
\n" ); document.write( "\"%28x+-+1%29%28x+-+%283%2F7%29%29+=+x%5E2+-%2810%2F7%29x+%2B+3%2F7\"
\n" ); document.write( "Multiplying both sides by 14,
\n" ); document.write( "\"14%2A%28x+-+1%29%28x+-+%283%2F7%29%29+=+14x%5E2+-+20x+%2B+6\"
\n" ); document.write( "So, 1 and 3/7 are the factors.
\n" ); document.write( "The other equation is factored in the same manner
\n" ); document.write( "
\n" );
