Answer:
P = x³ − 9x² + 36x − 54
Step-by-step explanation:
Complex roots come in conjugate pairs. So if 3−3i is a zero, then 3+3i is also a zero.
P = (x − 3) (x − (3−3i)) (x − (3+3i))
P = (x − 3) (x − 3 + 3i) (x − 3 − 3i)
P = (x − 3) ((x − 3)² − (3i)²)
P = (x − 3) ((x − 3)² + 9)
P = (x − 3)³ + 9 (x − 3)
P = x³ − 9x² + 27x − 27 + 9x − 27
P = x³ − 9x² + 36x − 54
I mean, this isn't a question but its true?
5p-30 is the simplification to this rather simple equation.
The answer is D.
3x + 2 > 14, id you plug in 5 for x, it is 3 x 5 > 14 and that is true.
10 - x < 7, If you plug 5 in, it turns into 10 - 5 < 7 and that is true.
