Question

3x^2 - 24 = 0 ......... Solve equation by taking square roots

Answer 1

x = 2 √ 2 , − 2 √ 2

Explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer 2

`\displaystyle x=\±2√(2)`

Explanation:

`3x^2-24=0`

`3x^2-24+24=0+24`

`3x^2=24`

`\displaystyle (3x^2)/(3)=(24)/(3)`

`x^2=8`

`x=\±√(8)`

`x=\±2√(2)`
