Use the FOIL method (distribution property):
First = x * x = x^2
Outer = x * 6 = 6x
Inner = 7 * x = 7x
Last = 7 * 6 = 42
x^2 + 6x + 7x + 42
x^2 + 13x + 42
The statement is true.

You can work out a quadratic equation using the formula shown at http://www.sosmath.com/algebra/quadraticeq/quadraformula/quadraformula.html
It's a lot easier than the factoring method, though a bit more complex.
P.S. Your answer IS correct!
