If the area of a square garden is 1/81km2
that means 2 sides were multiplied to find the area.
since it is a square all sides are the same, what number multiplied by itself equals 1/81...
1/9 x 1/9 equals 1/81
which means each side is 1/9km
You take 67 and multiply it by 60%
67 x 0.60 = 40
Zeros are
Write in factor form and solve
- (x-0)(x-(-3))(x-(-4))=0
- x(x+3)(x+4)=0
- x[x(x+4)+3(x+4)]=0
- x(x²+4x+3x+12)=0
- x(x²+7x+12)=0
- x³+7x²+12x=0
Points given (-2,16)
Solve for n
On solving we get
So the function is
- y=-4(x³+7x²+12x)
- y=-4x³-28x²-48x
