Factor completely and find the roots of the following. X^2+12x+27=0
1 answer:
Answer:
x = - 9, x = - 3
Step-by-step explanation:
Given
x² + 12x + 27 = 0
To factorise the quadratic
Consider the factors of the constant term (+ 27) which sum to give the coefficient of the x- term (+ 12)
The factors are + 9 and + 3, since
9 × 3 = 27 and 9 + 3 = 12, hence
(x + 9)(x + 3) = 0
Equate each factor to zero and solve for x
x + 9 = 0 ⇒ x = - 9
x + 3 = 0 ⇒ x = - 3

Step-by-step explanation:
find out f(2)
f(2)= (3×2×2) - 4= 8
then g(8) = 16 - 6= 10
No they cross each other like a highway. You are on the underpass and your friend passes over you. As in, they are crossing a bridge & you are below them.
