Write the equation of a quadratic with x-intercepts at (-1,0) and (4,0)

y = x² - 3x - 4

Step-by-step explanation:

Given that the x- intercepts are x = - 1 and x = 4, then the corresponding factors are

(x + 1) and (x - 4) and the quadratic is the product of the factors, that is

y = (x + 1)(x - 4) ← expand using FOIL

y = x² - 3x - 4

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.
