What is the solution set of the equation 3x^2 =48

x = ±4

Step-by-step explanation:

3x^2 =48

Divide by 3

3x^2/3 = 48/3

x^2 = 16

Take the square root of each side

sqrt(x^2) = ±sqrt(16)

x = ±4

x = ± 4

Step-by-step explanation:

You need to get by itself, and to do this, you divide both sides by 3, like so:

Now take the square root of both sides:

x = ± 4

the correct answer would be d because the slope is -2/2=1 and the y intercept is at 2 so that is the correction equation
