Answer:
x = 9
x = 3
Step-by-step explanation:
find the roots of x² - 6x - 27 = 0
by factorization (or use any of your favorite methods for solving quadratic equations):
x² - 6x - 27 = 0
(x-9)(x+3) = 0
Hence,
(x-9) = 0 --------> x = 9
or
(x+3) = 0 --------> x = -3
1. d/a+c=d
2. (m+21)/5=n
3. (1/2+2q)*4=p or 2+8q=p
4. (p-2a)/2pi=r
5. {[(5c+1)/2]+c}/3=a
