If \( x = -3 \), calculate the value of: \( x^3 + x \).

x 3 + x
x= -3
Plug the value of x into the equation. x = -3
After putting the value of x in it now looks like:
− 3 3 + ( − 3 )
Now solve: − 3 3 is the same as: (-3) x (-3) x (-3)
(-3) x (-3) x (-3) = -27
Finish the equation by adding -3 to -27 (same thing as subtracting 3 from -27) -27 + (-3) = -30
x = -30

3x+x=y 3(-3)+(-3)=y -9-3=y -12=y
Therefore the value of x3+x is -12
