Start by substituting 14 in for x everywhere that x appears in the problem.
So we have (14)² + 5(14) + 11.
Remember that PEMDAS tells you to deal
with your exponents before multiplying.
So you must square the 14 to get 196.
So we have 196 + 5(14) + 11.
Now multiply 5(14) to get 70.
So we have 196 + 70 + 11.
Now we can simply add to get 277.
