What is the value of 2x3 + x2 – x when x = 3?
Bad White [126]

Answer:

12

Step-by-step explanation:

This is assuming that x2 means x to the power of 2 and that the x on the left is to represent multiplying. First, plug in all of the number to get 2*3+3^2-3.Using PEMDAS, you should solve the exponent to get 9. Then, multiply 2 by 3 to get 6. Add 6 to 9 to get 15. Subtract 2 to 15 to get 12.

TL;DR

2*3+3^2-3

6+9-3

15-3
