Given the polynomial expression (2x^{2} - 3x + 5), evaluate the expression when (x = 3).

Question

Accepted Answer

Step:1 ：Substitute (x = 3) into the polynomial expression, so we have (2*(3)^{2} - 3*3 + 5).Step:2 ：Calculate the square and multiplication, we get: (2*9 - 9 + 5).Step:3 ：Perform the operations in the correct order (BIDMAS/BODMAS), so we have: (18 - 9 + 5).Step:4 ：Finally, subtract and add to get the answer: (9 + 5).
