show that:
x^2+x+k is prime,
x^2+(k+1)x +k is reducible for all positive intergers k.
x^2+x+k is prime,
x^2+(k+1)x +k is reducible for all positive intergers k.
Using the Quadratic Formula, <u>any</u> quadratic ax2+bx+c can be factored.Show that: x2+x+k is prime for all positive integers k.
The quadratic factors: .(x+1)(x+k)Show that: x2+(k+1)x+k is reducible for all positive intergers k.
