z2 - 4

first set up your parenthesis for factoring

( )( )

now put in your "z" in both first places in the parenthesis because this is obviously the only place it can go

(z )(z )

now find what can multiply to 4 and add or subtract to equal 0... the answer is -2 and 2 so put both these numbers in the remaining spots

(z - 2)(z + 2)

this is now in factored form

(z - 6)(z - 6)

(x - y - z)(x - y + z)

z2 + 9z + 18 = z2 + 6z + 3z + 18 = z(z+6) + 3(z+6) = (z+6)*(z+3)

its either (z2+ 9)(z - 2) , (z2+ 2)(z - 9) , or (z2- 9)(z - 2)

If you mean how do you factor z2 + 50z + 49, since the coefficient of z2 is 1, you just have to figure out what two numbers when multiplied together give you 49 and when added together give you 50. That's obviously 49 and 1. So... z2 + 50z + 49 = (z + 49)(z + 1)

z2 = z * z * 1; z = z * 1. Greatest common factor is z.

The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers or expressions. You have only one expression in the question! The greatest factor of any number is itself.

After all forces are summed with vector addition, the result is usually known as the net force (Fn) and can be used in the formula (Fn = ma).
