F(x) = x2 − 2x how would i factor this?

The only way to factor an equation such as this is by pulling out the greatest common factor. When we look at what is the largest term in both of these, we discover both have an x, but nothing else. So, we need to extract an x out of each piece.

f(x) = x^2 - 2x

f(x) = x(x - 2)

This will give you the fully factored form for this equation.

f(x) = x^2 - 2x ← Factor out a common factor in each, which is a x

= x(x - 2)

And there you go!

The mean of annual precipitation for the chihuahuan desert is 235 mm.

based on that, in about 6 years , the amount of rainfall that the desert has will range around :

approx. 235 mm x 6   = approx. 1410 mm
