To find the value of the expression (2x² + 3) when (x = 4), first substitute the value of (x) into the expression.

Calculate (x²):

[

x² = 4² = 16

]

Next, multiply this value by 2:

[

2x² = 2 \times 16 = 32

]

Finally, add 3 to this product:

[

2x² + 3 = 32 + 3 = 35

]

Therefore, the value of the expression when (x = 4) is 35. This aligns with the correct answer choice, indicating that the computation and substitution were properly executed, leading to the conclusion based on basic arithmetic operations applied to the expression.
