Question

will give metal to best answer. please solve y^2 + 2y + 5 for y = -5

Answer 1

What you do is replace each copy of 'y' with -5 (since y = -5) and evaluate

y^2 + 2y + 5

(-5)^2 + 2(-5) + 5

25 + 2(-5) + 5

25 - 10 + 5

I'll let you finish up

Answer 2

you are given this equation:
y^2 + 2y + 5
every where you see a 'y' replaces it with a (-5) becuase of this equation given to you:
y = -5
