I am gonna have to go with Latisha's answer.
(x - 3)(x + 4) = x^2 + 4x - 3x - 12 = x^2 + x - 12.......and 4(-3) = -12, -3 + 4 = 1....and the factors are correct
children playing soccer, m
number of teams = 4
number if kids per team, f(m) = m/4
X^4 - 4x^3 - 9x^2 + 36x = 0
x(x^3 - 4x^2 - 9x + 36) = 0
x(x^2(x - 4) - 9(x - 4) = 0
x(x + 3)(x - 3)(x - 4) = 0
the zeroes are -3, 0, 3, 4 Answer

I just solved it by my mind you just check it
Answer:
we will need 7 bags
Step-by-step explanation:
To solve this problem we first have to calculate the total area of the garden
a = area
b = base = 8m
h = height = 12.5m
a = b * h
we replace with the known values
a = 8m * 12.5m
a = 100m²
Now that we know the total area of the garden and the area occupied by a single bag, we divide the total area by what a bag covers.
100m² / 16m² = 6.25 bags
because we cannot buy a fraction of a bag we will need 7 bags
