Best ResponseYou've already chosen the best response.0yeah, take square root on both sides of \((4x+1)^2=20\) what do you get ?

Best ResponseYou've already chosen the best response.0that would be \(4x+1 =\pm \sqrt {20}\) ok? now subtract 1 from both sides, what u get ?

Best ResponseYou've already chosen the best response.0thats correct, now just divide both sides by 4 and you get 2 values of x.

Best ResponseYou've already chosen the best response.0? how ? \(4x=\pm \sqrt{20}1 \implies x = \dfrac{\pm \sqrt{20}1}{4}\)

Best ResponseYou've already chosen the best response.0so is it 19 divided by 4

Best ResponseYou've already chosen the best response.0no, it'll only be \( x = \dfrac{\pm \sqrt{20}1}{4}\) or one simplification will be \( x = \dfrac{\pm 2\sqrt{5}1}{4}\)
