Solve the equation : x^(2)+5=3(x^(2)-3)

Fittoniya [83]

Answer:

x = ± 2

Step-by-step explanation:

Given

x² + 5 = 3x² - 3 ( subtract x² + 5 from both sides )

0 = 2x² - 8 ( add 8 to both sides )

8 = 2x² ( divide both sides by 2 )

4 = x² ( take the square root of both sides )

x = ± $\sqrt{4}$ = ± 2
