What is the factored equation for f(x)=x+x-6

f(x)=2(x-3) yup that's the answer

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

using pemdas, (order of operations) you'll see the answer is 24.
