You can put this solution on YOUR website!
Whenever you are given a quadratic equation in which you cannot factor, we can solve it using the quadratic formula
\n" ); document.write( "(Note the quadratic formula states that if I have a quadratic in the form
\n" ); document.write( " $\"ax%5E2%2Bbx%2Bc=0\"$
\n" ); document.write( "then
\n" ); document.write( " $\"x=%28-b+%2B-+sqrt%28b%5E2-4ac%29%29%2F2a\"$ \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So in our case our a=8 our b=3 and our c=-4. From here it is just substituting these three values into the equation above and using your calculator**make sure you put brackets in the correct positions when using the calculator or else it may calculate a different value**)\r
\n" ); document.write( "
