Question

answer me fast I am giving test ​

Answer 1

Answer:

(x-1)x(x+1)+(x+1)x(x+1)x(x+1)=0

(x-1)x(x+4)=1

x-1-1=x+4

x2=x+4

x=2+4

x=6

Answer 2

Answer:

HII! SLATA HERE'S YOUR ANSWER

=(X-1)²(X+1)³(X-4)<0

By using ALGEBRAIC IDENTITY

(a-b)²=a²+b²-2ab

AND

(a+b)³=a³+b³+3a²b+3ab²

=x²+1-2x × x³+1+3x²+3x × x-4 <0

Now, solve it own girl.
