Best ResponseYou've already chosen the best response.01. Make the equation equal to \(0\) first. Since it is \(x^22x=24\), make it equal to zero by SUBTRACTING \(24\) on both sides.dw:1442444154016:dw

Best ResponseYou've already chosen the best response.0Now let's factor this equation. :) What two numbers will you MULTIPLY to get \(24\)?

Best ResponseYou've already chosen the best response.06 and 4 are partially correct! But if you add 6 and 4, would you get 2? Yes or no?

Best ResponseYou've already chosen the best response.0ok, i kinda get it but i have a question. if you added 6 and 4, why would you get 2?

Best ResponseYou've already chosen the best response.0When you \(6\) and \(4\) you will not get 2, but you will get 10 because \(\huge 6+4=10\).

Best ResponseYou've already chosen the best response.0well yes XD so you're trying to get to 2 as well?

Best ResponseYou've already chosen the best response.0Like that is your goal?

anonymous

Best ResponseYou've already chosen the best response.0Yes! You want to get 2 when you add them and at the same time get 24 when you multiply them. :D

Best ResponseYou've already chosen the best response.0so are you now trying to get to 24? so the answer would be x=6,4?

Best ResponseYou've already chosen the best response.0"so are you now trying to get to 24?" No. We've already done that because \(\huge (6)(4)=24\)

Best ResponseYou've already chosen the best response.0"so the answer would be x=6,4? CORRECT! We're trying to solve for x. :)
