Answer:±2 sqrt(3) =x

Step-by-step explanation:12 – x^2 = 0

Add x^2 to each side

12 – x^2 + x^2 = x^2

12 = x^2

Take the square root of each side

±sqrt(12) = sqrt(x^2)

±sqrt(4*3) = sqrt(x^2)

±sqrt(4) sqrt(3) = x

±2 sqrt(3) =x

Answer:

x = -2sqrt(3), 2sqrt(3)

Step-by-step explanation:

12 – x² = 0

x² = 12

x = +/- sqrt(12)

x = +/- 2sqrt(3)

sqrt: square root
