Answer:

2√3 or -2√3

Step-by-step explanation:

To find the value of x, we must make x the subject of the formula or equation. this will be done by making x stand alone.

Given that 3x² + 4 = 40

3x² = 40 - 4

3x² = 36

x² = 12

x = ±√12

x = ±2√3

x = 2√3 or -2√3

It means that x has 2 possible values.
