Best ResponseYou've already chosen the best response.1the numerator 3x6 can be factored 3 and 6 have the factor 3 in common, so we can factor out this common factor 3x6 = 3(x2) notice if you were to distribute the 3 back in, you'd get 3x6

Best ResponseYou've already chosen the best response.1the `x2` terms will divide to 1 recall that x/x = 1 in english: "any term, except 0, divided by itself will give you 1"

Best ResponseYou've already chosen the best response.1are you able to factor \[\Large x^2+3x10\] at all?

Best ResponseYou've already chosen the best response.1oh and I nearly forgot: for #8, the excluded value is x = 2. This value must be excluded to avoid dividing by zero

Best ResponseYou've already chosen the best response.0so the answer is x = 2

Best ResponseYou've already chosen the best response.1no I'm saying that x = 2 is kicked out because if x = 2, then the denominator x2 turns to 0 (we can't divide by zero). This is all for #8

Best ResponseYou've already chosen the best response.1\[\Large \frac{3x6}{x2}\] simplifies to 3 (as shown above in the drawings). The restriction is that \(\large x\ne 2\)

Best ResponseYou've already chosen the best response.0if you showed me how to do it step by step 1.) 2.) 3.) I would know how to do it

Best ResponseYou've already chosen the best response.1yes, 2*5 = 10 2+5 = 3

Best ResponseYou've already chosen the best response.1since the two numbers are 2 and 5, this means x^2+3x10 factors to (x2)(x+5)

Best ResponseYou've already chosen the best response.1like in #8, the `x2` terms divide to 1 and cancel out effectively dw:1441071502600:dw

Best ResponseYou've already chosen the best response.1so hopefully you see how \[\Large \frac{x2}{x^2+3x10} = \frac{1}{x+5}\] the restrictions are that \(\large x \ne 2\) or \(\large x \ne 5\) to avoid division by zero errors
