The zeroes are
0, -5, 3 + i (and its conjugate)
The factors are
x (x + 5) (x - (3 + i)) (x - (3 - i))
Expanding...
(x² + 5x)((x - 3) - i) ((x - 3) + i)
(x² + 5x)((x - 3)² - i²)
(x² + 5x)(x² - 6x + 9 - (-1))
(x² + 5x)(x² - 6x + 10)
x⁴ - 6x³ + 10x² + 5x³ - 30x² + 50x
x⁴ - x³ - 20x² + 50x
Answer:arithmetical division in which the divisor has two or more figures, and a series of steps is made as successive groups of digits of the dividend are divided by the divisor, to avoid excessive mental calculation.
Step-by-step explanation:
d) neither parallel or perpendicular
Answer:
c. 120 units^3
Step-by-step explanation:
L x W x H = <em>V</em>
3 x 4 / 2 = 6
6 x 20 = 120
i believe it would be 5.25
12-5=7
7*12=84
84/ 16 = 5.25
i hope this helps
