You can put this solution on YOUR website!
Use the discriminant to determine the nature of the rools of each equation.
\n" ); document.write( ":
\n" ); document.write( " 10x^2 + x = 21
\n" ); document.write( "Put the equation in the standard form:
\n" ); document.write( "10x^2 + x - 21 = 0
\n" ); document.write( ":
\n" ); document.write( "Using the form ax^2 + bx + c, in your equation: a = 10, b = 1, c = -21
\n" ); document.write( ":
\n" ); document.write( "The discriminant: D = b^2 - (4 * a * c)
\n" ); document.write( ":
\n" ); document.write( "D = 1^2 - (4 * 10 * -21)
\n" ); document.write( "D = 1 - (- 840)
\n" ); document.write( "D = 1 + 840
\n" ); document.write( "D = +841
\n" ); document.write( ":
\n" ); document.write( "Since D > 0, there are 2 real number solution that are not equal.\r
