Best ResponseYou've already chosen the best response.0now move your terms all to one side and set it equal to 0 and factor or use the quadratic to solve for x

Best ResponseYou've already chosen the best response.0actualy... i typoed.. it should be \[x+10=x^{2}4x+4\]

Best ResponseYou've already chosen the best response.0and the only reason i move to the right is cause I dont want to multiply by a negative 1.

Best ResponseYou've already chosen the best response.0ok. i would factor this. so you set up parens.. ( )( ) right? fill them with (x )(x ). now we are looking for 2 numbers that multiply to 6 and add to 5

Best ResponseYou've already chosen the best response.0so 2 and 3 seem to work nice.. but they are not gonna get us to where we want because of the negative 5. so we try 1 and 6. (x 1)(x 6) right?

Best ResponseYou've already chosen the best response.0now since we know we a negative 5.. we know that 6 has to be negative. so (x+1)(x6)

Best ResponseYou've already chosen the best response.0solve those as separate equations .. x6=0 and x+1=0

Best ResponseYou've already chosen the best response.0yep. now.. the most important.. you need to plus these numbers back into the equation.. to check if both answers work.

Best ResponseYou've already chosen the best response.0so x = 6 is your only answer? does that make sense?

Best ResponseYou've already chosen the best response.0\[\sqrt{9} =3 \neq 12 = 3\] \[\sqrt{16}=4 = 62=4\]
