Answer:
216 + 9i
Step-by-step explanation:
Given: f(x) = 3x² + 3 + 3x
When x = -9, f(x) equals to;
3(-9)² + 3(-9 + 3(-9)
243 + 3(3i) - 27
243 + 9i - 27
216 + 9i
(x + 7) (x - 4)
First, apply the FOIL method (a + b) (c + d) = ac + ad + bc + bd / Your problem should look like:
- 4x + 7x - 28
Second, gather the like terms. / Your problem should look like: + (-4x + 7x) - 28
Third, simplify. / Your problem should look like: + 3x - 28
Answer: + 3x - 28
