Algebra Help Kids
trying to understand how to figure out this problem. Its not homework I am trying to understand algebra for my kids AHHHHH!
x2-x-6/x2-4
Is this possible how the heck do you subtract letters?
ok u have to factor top and bottom
x^2-1x-6 tell me 2 #s that muliply to -6 and add together to -1
= (x-3)(x+2)
x^2-4 = (x-2)(x+2)
so
x2-x-6/x2-4=(x-3)(x+2)/(x-2)(x+2)
the x+2s simplify
so x-3/x-2 is the answer
