Question

Answer please I’m really struggling with this

Answer 1

To write the any polynomial in standard form you must first put it in terms separated only by $+,-$ operators, then you must order terms $x^n$ descendingly according to $n$. In your case $-\frac{1}{5}x^2$ will be the first term because it has highest power, followed by $-8x^1$ and $+7x^0$.

The standard form of this specific polynomial is:

$-\dfrac{1}{5}x^2-2x+7$.

Hope this helps.
