What is the solution set of the following equation?
(2x - 5)(3x + 1) = 0 **Weegy:** x = 27/4 **User:** Choose the equation that models the following problem.
When the side of a square is doubled, its area is increased to 28 cm2.
2x= 28
2x2= 28
(2x)2= 28
2x=x2+ 28 **Weegy:** The sides of the square are both 8cm(its a square, and 8 squared is 64)
So the diameter of the circle is 8cm, and the radius is 4.
The area = pi(4^2) = 16pi. **User:** Determine the solution set of (x + 2)2 = 36. (More)

(2x - 5)(3x + 1) = 0

2x - 5 = 0 or 3x + 1 = 0

x = 5/2 or x = -1/3

The solution set for the equation (2x - 5)(3x + 1) = 0 is {5/2, -1/3)

2x - 5 = 0 or 3x + 1 = 0

x = 5/2 or x = -1/3

The solution set for the equation (2x - 5)(3x + 1) = 0 is {5/2, -1/3)
