Answer:

use identity (a - b) ^3 = a^3 - b^3 - 3ab (a - b)

here, a = x ^2

b = -1

= (x^2)^3 - (-1)^3 - 3 * x ^2 * -1 ( x^2 - (-1) )

x^6+ 3 x^2 ( x ^2 + 1)

I think this is the answer

Can i get help on these
JulsSmile [24]

Answer:

a) \frac{32}{21}

b) -14

c) -3

d) -96

Step-by-step explanation:

a) The parenthesis indicate multiplication.

b) Minus and plus gives subtraction, and the sign you put behind the number is the sign of the largest number you have (in this case it's 21 since we ignore the -)

c) They already have common denominators, all that's left is to do \frac{-7 -2}{3} = \frac{-9}{3} = -3

d) The parenthesis indicate multiplication.

Good luck!
