C + H2 → CH4 balance the equation

Step-by-step explanation:

hg(x) means you multiply h(x) times g(x) and then we will set it equal to .

hg(x) = which simplifies to

. Now set that equal to :

and get everything on the same side and factor:

. Factor by grouping:

and factor out what's common in each set of ( ):

which factors out to

. But factors somoe to:

(x + 1)(x - 1)(x - 1) = 0 So the solutions for this are

x = -1, 1
