LQR and MPC is equal if the MPC controller has no constraints(e.g saturation on inputs/outputs).
But LQR is closed loop feedback by using the LQR control law matrix. MPC is open loop, which means no feedback system.

Use the definition of absolute value to evaluate $| 20 |$. Then, you add a negative sign to the answer.
#### Explanation:
The definition of absolute value is how far a number is from $0$.
