( 4 / 5 )^-2 = ( 5 / 4 )^2 = 25 / 16 ;
Step-by-step explanation:
x⁴ − 5x³ + 11x² − 25x + 30
x⁴ − 5x³ + 6x² + 5x² − 25x + 30
x² (x² − 5x + 6) + 5 (x² − 5x + 6)
(x² + 5) (x² − 5x + 6)
(x² + 5) (x − 2) (x −3)
The zeros are 2, 3, and ±√5i.
According to my calculations the 30% of 570 is 171
10% of 570 is 57
times that by 3 and you get 171
