Question

(5-x) (6-5x) (2-x) please solve this problem​

Answer 1

Step-by-step explanation:

(5 – x) (6 – 5x) (2 – x)

[(5 – x) (6 – 5x)] (2 –x)

[5(6 – 5x) – x (6 – 5x)] (2 – x)

[30 – 25x – 6x + 5x2] (2 – x)

(5x2 – 31x + 30) (2 – x)

2(5x2 – 31x + 30) – x(5x2 – 31x + 30)

10x2 – 62x + 60 – 5x3 + 31x2 – 30x

-5x3 + 10x2 + 31x2 – 62x – 30x + 60

-5x3 + 41x2 – 92x + 60
