42. Find b^2 - 4ac and the number of real solutions to each equation.
\n" ); document.write( "If you have a quadrate: y = ax^2 + bx + c
\n" ); document.write( "The roots are x = [-b +- sqrt(b^2-4ac)]/(2a)
\n" ); document.write( "---
\n" ); document.write( "If b^2 - 4ac = 0 the two roots are both x = -b/2a
\n" ); document.write( "---
\n" ); document.write( "If b^2 - 4ac > 0 you will have two Real Number solutions
\n" ); document.write( "---
\n" ); document.write( "If b^2 -4ac < 0 you will get two Complex Number solutions
\n" ); document.write( "-----------------------------------------------------------------
\n" ); document.write( "14. Solve each equation by using the quadratic formula.
\n" ); document.write( "-8q^2+2q+1=0
\n" ); document.write( "x = [-2 +- sqrt(4 - 4*-8*1)]/(-16)
\n" ); document.write( "---
\n" ); document.write( "x = [-2 +- sqrt(36)]/(-16)
\n" ); document.write( "---
\n" ); document.write( "x = [-2 +- 6]/(-16)
\n" ); document.write( "---
\n" ); document.write( "x = [-8/-16] or x = [4/-16]
\n" ); document.write( "x = 1/2 or x = -1/4
