Best ResponseYou've already chosen the best response.2Add the 5 and set your polynomial to zero.

Best ResponseYou've already chosen the best response.2\[x^2+6x+5 =0\] notice that it's in the form: \[ax^2+bx+c\] to factor, you must find TWO numbers whose product is "c", but the sum of the two terms, result in "b". Does that make sense? It means: n x n = c, but n + n = b

Best ResponseYou've already chosen the best response.2where the n's are two constants. meaning numbers  obviously.

Best ResponseYou've already chosen the best response.1But...that's for factoring right? I need to find the value of x...

Best ResponseYou've already chosen the best response.2Yes, to find the value(s) of "x". You need to factor.

Best ResponseYou've already chosen the best response.2quadratic formula usually makes the algebra more tedious. It's best if you factor.

Best ResponseYou've already chosen the best response.1Okay, I'm coming up with jibberish. Could you walk me through it?

Best ResponseYou've already chosen the best response.2make a list of factors of 5

Khaleesi

Best ResponseYou've already chosen the best response.2yes. so (x + 1)(x + 5) = 0 now you can set those two factors (x + 1 and x + 5) set to 0 and solve for x

Best ResponseYou've already chosen the best response.2right, but you couldn't use 1 and 5 because those don't add up to 6

Best ResponseYou've already chosen the best response.2so solve for x in both x + 5 = 0 and x + 1 = 0 and they will be your answers
