Find the x intercepts
\n" ); document.write( "f(x)=2x^2 +8x-42
\n" ); document.write( "---
\n" ); document.write( "Let y = 0
\n" ); document.write( "2x^2 + 8x - 42 = 0
\n" ); document.write( "2(x^2 + 4x - 21) = 0
\n" ); document.write( "Factor:
\n" ); document.write( "2(x+7)(x-3) = 0
\n" ); document.write( "x = -7 or x = 3
\n" ); document.write( "========================
