Question

solve the equation z^2 - 6z -27= 0 by factoring

Answer 1

(z+3)*(z-9)

Answer 2

if it in standard form
ax^2+bx+c
you can factor using this form
(z+f)*(z+g)
you have to find f and g to add up and produce c and b
3 and -9 produce C
and add up to b

Since you dont have an a coeffecient you dont have to worry about it here.
