Question

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

Answer 1

Answer:

x = 2 √ 2 , − 2 √ 2

Step-by-step explanation:

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

Answer 2

Answer:

$\displaystyle x=\±2\sqrt{2}$

Step-by-step explanation:

$3x^2-24=0$

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

$3x^2=24$

$\displaystyle \frac{3x^2}{3}=\frac{24}{3}$

$x^2=8$

$x=\±\sqrt{8}$

$x=\±2\sqrt{2}$
