Answer:
x^4 - 10 x^3 + 23 x^2 + 20 x - 50
Step-by-step explanation:
https://www.wolframalpha.com/input/?i=simplify+(x-5)%5E2+*+(+x-+sqrt(2))*(+x%2B+sqrt(2))
5y-1
3y+3y+5+7x^3-y-6-7x^3
3y+3y-y= 5y
7x^3-7x^3 cancel each other out
5-6= -1
d
=1000
10^3 is 1000
sorry, the answer is undefined because negative in squer is undefined
