You can't simplify it any further without a value for y.
a(a^2 + 1)
(x - 1)(x - 1)(x - 1) - (x + 1)(x + 1)(x + 1)
(X + 1)3 = X3 + 3X2 + 3X + 1
(x - 1)(2x^2-1)
If that's 5x2, it factors to (x + 5)(x2 + 1)
No.
Just remember the basic rule : When dividing by a fraction, invert the fraction and multiply. 40x/64y ÷ 5x/8y = 40x/64y * 8y/5x = 320xy/320xy = 1
a(a^2 + 1)
sin cubed + cos cubed (sin + cos)( sin squared - sin.cos + cos squared) (sin + cos)(1 + sin.cos)
9y cubed plus 2y squared
The answer is 100.
(x - 1)(x - 1)(x - 1) - (x + 1)(x + 1)(x + 1)
3-cubed plus 2 plus 1 plus 4= 34
(X + 1)3 = X3 + 3X2 + 3X + 1
2 cubed = 2*2*2 =8. 8+8+8= 24
(x - 1)(2x^2-1)
(2x + 1)(4x^2 - 2x + 1)
