Question

\(\left(4x+2\right)^2=36\)

Answer 1

\(\left(4x+2\right)^2=36\)

\(\Rightarrow4x+2=6\)hoặc \(4x+2=-6\)

\(\Rightarrow4x=4\) hoặc \(4x=-8\)

\(\Rightarrow x=1\) hoặc \(x=-2\)

Answer 2

(4x+2)²=36

(4x+2)²=6² hoặc (4x+2)²=(-6)²

=>4x+2=6 hoặc 4x+2=-6

   4x=4 hoặc 4x-8

     x=1 hoặc x=-2

Answer 3

\(\left(4x+2\right)^2=36=6^2\)

\(\Rightarrow4x+2=6\)

\(\Rightarrow4x=4\)

\(\Rightarrow x=1\)

Answer 4

( 4x + 2 ) ^2 = 36 = 6^2

4x + 2 = 6

4x=4

x=1
