Question

solve
3 square root 2x +1 =3
2x +1 under the sqaure

Answer 1

3 square root( 2 x + 1 ) = 3 square both sides

3 ^ 2 * square root( 2 x + 1 ) ^ 2 = 3 ^ 2

9 * ( 2 x + 1 ) ^ 2 = 9 Divide both sides by 9

2 x + 1 = 1 Subtract 1 to both sides

2 x + 1 - 1 = 1 - 1

2 x = 0 Divide both sides by 2

x = 0
