3x^2-192=0 3 {x}^(2) - 192 = 0

Question

3x^2-192=0

`3 {x}^(2) - 192 = 0`

Answer 1

`3 {x}^(2) - 192 = 0 \\ 3 {x}^(2) = 192 \\ {x}^(2) = 64 \\ \\ x _{ _(1) } = - 8 \\ x _{ _(2) } = 8`

hope it's correct

Answer 2

`3x^2-192=0`

`3x^2=192`

`x^2=(192)/(3)`

`x=\pm √(64)`

`x=\pm 8`

x=-8 and x=8 are the solutions
