Evaluate the expression when x= -7. x²+4x-3

49+(-29)-3.

The answer is -80

Step-by-step explanation:

1. What I did first was plug in -7 into "x", so then your  expression is

2. Then you multiply 7 two times and get - 49... So then you have -49+4(-7)-3

3. Then you multiply the 4 and -7 and get -29... So now you have -49+(-29)-3

4. Then you add -49 and -29. but keep the negative and get -77... so now you have -77-3

5. Then you add -77-3 but keep the negetive and get -80.

I hope this helps... have a wonderful day.
