What is the equation of the line?

y=(x−2)(x+1)2(x+3)y=\left(x-2\right)\left(x+1\right)^2\left(x+3\right)

y=(x−2)(x+1)(x+3)y=\left(x-2\right)\left(x+1\right)\left(x+3\right)

y=−(x+2)(x−1)(x−3)y=-\left(x+2\right)\left(x-1\right)\left(x-3\right)

y=−(x+2)(x−1)2(x−3)y=-\left(x+2\right)\left(x-1\right)^2\left(x-3\right)
