Answer:
A. x²-7x-18=0
Step-by-step explanation:
cuz it has a value of b in the equation and in the standard form you have to find where is the value of b like this:
a=1 why 1 cuz tye variable of x is 1
b= -7 u don't have to place the x in there
c= -18
if u see a value of b (-7) that is a standard form and if u only see like ( x²+18=0 ) this is not a standard form u are going to find the value of b.
