We need to evaluate the expression 5x² + 3x + 2 when x = -2.

Step 1: Substitute -2 into the expression:
  5(-2)² + 3(-2) + 2

Step 2: Compute (-2)²:
  (-2)² = 4

Step 3: Multiply by 5:
  5 × 4 = 20

Step 4: Multiply 3 by -2:
  3 × (-2) = -6

Step 5: Combine all terms:
  20 + (-6) + 2 = 20 - 6 + 2 = 16

Thus, the value of the expression when x = -2 is 16.
The value of the expression $$ 5x^{2} + 3x + 2 $$ when $$ x = -2 $$ is 16.

Find the value of the expression \( 5 x^{2}+3 x+2 \) when \( x=-2 \). \( \begin{array}{l}-30 \\ 0-32 \\ 0 \\ 10 \\ 16 \\ 08\end{array} \)
