Question

Evaluate the following expression when x=14. X^2+5x+11

Answer 1

277

Explanation:

14^2+5(14)+11=

196+70+11=

277

Answer 2

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.
