EXPLANATION
This is a quadratic function, because it has two 'x' multiplying in different terms.
The standard form of a quadratic function is:
![ax^2+bx+c](https://tex.z-dn.net/?f=ax%5E2%2Bbx%2Bc)
To transform this expression in standard form we have to apply the distributive property to multiply the terms in the parenthesis:
So for this expression a = 2, b = 7 and c = 5.
Answer- 2: x-1
When there is a " - " in front of the parenthesis change the sign of each term in parentheses
