Question

(4x+1)^2=20 solve each equation by the square root property

Answer 1

did you take square root on both sides, first ? what you get ?

Answer 2

solve for X i mean

Answer 3

yeah, take square root on both sides of \((4x+1)^2=20\)
what do you get ?

Answer 4

not sure

Answer 5

4x-1=\[\sqrt{20}\] =

Answer 6

that would be \(4x+1 =\pm \sqrt {20}\)
ok?
now subtract 1 from both sides, what u get ?

Answer 7

4x=\[\pm \sqrt{20}\] - 1

Answer 8

thats correct, now just divide both sides by 4 and you get 2 values of x.

Answer 9

i got x = PM square root 4

Answer 10

? how ?
\(4x=\pm \sqrt{20}-1 \implies x = \dfrac{\pm \sqrt{20}-1}{4}\)
