I need alot of help with f(x) = x2 + 9x – 36 because i have an assignment due later tonight and it will bring my grade down majorly

Sagot :

Answer:

so if the x2 is x squared and you are trying to find the values of x where f(x) is 0 then they are -12 and 3

Step-by-step explanation:

we can factor these into (x+12)(x-3)

in order for (x+12)(x-3) to be 0 then one of them has to be 0

first is (x+12) = 0 so x is -12

second is (x-3) = 0 so x is 3
