Answer:
2
Step-by-step explanation:
1. Substitute c with -6... so the equation would be -6^2 + 7(-6) + 8
2. Simplify... so -6^2 is 36 because when you square something you times it by itself and two negatives multiplied together equals a positive so -6*-6=36 then 7*-6 is -42 because a positive multiplied by a negative is always a negative
3. So now you have 36 + -42 + 8 or 36 - 42 +8 because an when adding a negative it’s basically just like subtracting because they cancel out
4. So when you simplify it’s simply it’s simply 2 because 36-42 is -6 added by 8 is 2
Sorry if this was confusing I’m really bad at explain gm but hope this helps :)
Hey there!
c^2 + 7c + 8
= -6^2 + 7(-6) + 8
= -36 - 42 + 8
= -78 + 8
= -70
Therefore, your answer is: -70
Good luck on your assignment & enjoy your day!
