She had $328 and now has $298 left. Simply subtract the two.

328 -298 = 30

To check it,

298 + 30 = 328

So, Tammy withdrew $30, and now has $298 left in her account.

Easy
quadratic means 2nd degree

means highest power of exponent is 2
so like x^2

first one
we have 3x^3, that is 3rd degree,nope

2nd one
we have 8x^4, nope, that is 4th degree

3rd one
we have -x^2, yep

4th one, we have 9x^4, that is 4th degree

answer is 3rd one or p(x)=-5x-x^2
