x cubed, or x³
If x is equal to 5, then x squared plus 25 is equal to 50.
8 + X SQUARED
I think you've left out something. Is one of the "x" functions squared?
x2 + 8x2 = 9x2
x[x+1] squared Simplified is, to my knowledge, x squared plus ( x + 1) squared
No
x2 + 4x = x(x+4)
Factor it out: (x+2) squared
Factorise it: (x + 5)(3x - 8)
My iTouch calculator isn't working, so I will simplify the problem for you: x to the 5th power = -4
simplify the square foor of 49 times x to the third time y to the sixth times the absolute value of z squared
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
The square root of x12 is x6 .
7(3y-2)-(-4y+9)
x^2-4x/x^2-6x+8 = x(x-4)/(x-2)(x-4) = x/(x-2)
3x
