Write a quadratic function in standard form with zeros 9 and -3 PL HELPP MEEE

f(x)=x^2-6x-27

Step-by-step explanation:

x=9 and x-3

set the equal to zero: x-9=0 and x+3=0

x-9 and x+3 are now the factors of your equation:

you equation so far is: (x-9)(x+3)=0

next factor these together to get: f(x)=x^2+3x-9x-27

finally simplify the equation leaving you with f(x)=x^2-6x-27

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
