Question

Simply the polynomial -3^2 + 4^f - 3 + 8f^2 + 7f + 1

a) 5f^2 - 11f + 2
b) 11f^2 + 11f + 2
c) 5f^2 + 11f - 2
d) -5f^2 + 3f - 2

Answer 1

Try to combine like terms.

Is the first term supposed to be -3f^2? If so, then 8f^2 - 3f^2 = 5f^2

Is the second term supposed to be 4f? If so, then 4f + 7f = 11f

That leaves: -3 + 1 = -2

Putting it all together, you have this:

5f^2 + 11f - 2 (choice c)

I hope this helps and is what you were asking.
