Answer:

34

Explanation:

In order to solve the equation, all you would have to do is substitute your answer by the number given. It would look something like this:

(4)^2+6(4)-6

Remember to follow PEMDAS when solving it.

(4)^2 --> 4*4=16

6(4)=24

16+24-6=34

So, your final answer would be 34.

Answer:

34

Explanation:

In order to solve this problem, you would have to plug-in 4 in letter c.

So the equation would go from:

c² + 6c - 6 to

(4)² + 6(4) - 6

4 to the square power is 16

6 times 4 is 24

So you would write this equation next
16 + 24 - 6

after adding and subtracting you should get 34 as your final answer.

Hope this helps!
