how many solutions are in the solution set for the equation 3x^2=21

Answer 1

To find the number of solutions in the solution set for the equation 3x^2 = 21, we need to solve the equation.

Dividing both sides of the equation by 3, we get:

x^2 = 7

Taking the square root of both sides of the equation, we have:

x = ±√7

Thus, there are two solutions in the solution set for the equation 3x^2 = 21, which are x = √7 and x = -√7.
