Step 2: Substitute the value of x, which is 3, into the expression. This gives us 2(3^2) - 5.
Step 3: Calculate 3^2, which is 9.
Step 4: Now replace 3^2 with 9 in the expression. It becomes 2(9) - 5.
Step 5: Multiply 2 by 9, which equals 18.
Step 6: Now the expression is 18 - 5.
Step 7: Subtract 5 from 18, which gives us 13.
