If that were z^2 - 16z + 64, it would factor very neatly to (z - 8)(z - 8) or (z - 8)^2
As it is, you could use z(z^2 - 16) + 64 or the much more cumbersome
-1/27 (3 z+2 2^(2/3) (3 (9-sqrt(69)))^(1/3)+4 3^(2/3) (2/(9-sqrt(69)))^(1/3)) (-9 z^2+(12 3^(2/3) (2/(9-sqrt(69)))^(1/3)+6 2^(2/3) (3 (9-sqrt(69)))^(1/3)) z-8 2^(1/3) (3 (9-sqrt(69)))^(2/3)-48 3^(1/3) (2/(9-sqrt(69)))^(2/3)+48)

Factor the following expression ax plus ay minus AZ?
ax + ay - AZ = a(x + y - z)
What is the least common multiple of x squared y cubed and z?
Their product.
How do you factor a monomial of 24z2?
2 x 2 x 2 x 3 x z x z = 24z2
How do you factor 4y squared minus 9?
To raise to a power it's a lot clearer if you use ^ on a PC. For example, x^2 for x squared. I think you want to factorise 4x^2 - 25(y^2)(z^2). We recognise this as a difference of squares: (2x)^2 - (5yz)^2 and so it factorises as (2x - 5yz)(2x + 5yz).
What times what minus what would equal to 13?
To solve the equation "x times y minus z equals 13," we need to set up the equation as follows: xy - z = 13. Since we are looking for three unknowns, there are multiple solutions to this equation. One possible solution could be x = 5, y = 3, and z = 2, as 5 times 3 minus 2 equals 13.
