Answer:
x is 7 in this question...
Answer:
x = -1, 3, and 7
Step-by-step explanation:
Using grouping:
f(x) = x³ − 9x² + 11x + 21
f(x) = x³ − 9x² + 18x − 7x + 21
f(x) = x (x² − 9x + 18) − 7 (x − 3)
f(x) = x (x − 6) (x − 3) − 7 (x − 3)
f(x) = (x² − 6x) (x − 3) − 7 (x − 3)
f(x) = (x² − 6x − 7) (x − 3)
f(x) = (x + 1) (x − 7) (x − 3)
To use long division, see the picture.
The zeros are x = -1, 3, and 7.
Answer:
area = 77 m²
