Question

[1-{1-(1-x2)-1}-11-12 is equal to
a. X
b. 1/x
&c. 1
d. None of these​

Answer 1

Answer:

-21-x^2

Step-by-step explanation:

I think there may be error in typing as the first bracket is not closed anywhere, therefore assuming it to be in end

[1-{1-(1-x^2)-1}-11-12]

Open brackets

Starting from smallest bracket

[1-{1-1+x^2-1}-11-12]

[1-{0+x^2-1}-11-12]

[1-{x^2-1}-11-12]

[1-x^2+1-11-12]

1+1-11-12-x^2

-21-x^2
