You can put this solution on YOUR website!
hopefully you mean x^2 + 6x + 9
\n" ); document.write( "since 3 * 3 = 9 and 3 + 3 = 6, then your factors probably be:
\n" ); document.write( "(x + 3) and (x + 3)
\n" ); document.write( "your equation is:
\n" ); document.write( "x^2 + 6x + 9
\n" ); document.write( "set it equal to 0 to get:
\n" ); document.write( "x^2 + 6x + 9 = 0
\n" ); document.write( "now factor it to get:
\n" ); document.write( "(x + 3) * (x + 3) = 0
\n" ); document.write( "this equation will be equal to 0 if:
\n" ); document.write( "(x + 3) = 0.
\n" ); document.write( "when (x + 3) = 0, then:
\n" ); document.write( "x = -3
\n" ); document.write( "the solution to your equation is x = -3.
\n" ); document.write( "if you want to confirm that solution is valid, then replace x with -3 in the original equation and solve.
\n" ); document.write( "you will get:
\n" ); document.write( "x^2 + 6x + 9 = 0 becomes:
\n" ); document.write( "(-3)^2 + 6*(-3) + 9 = 0 which becomes:
\n" ); document.write( "9 - 18 + 9 = 0 which becomes:
\n" ); document.write( "18 - 18 = 0 which becomes:
\n" ); document.write( "0 = 0
\n" ); document.write( "this confirms the value of x = -3 is a solution to your equation.\r
