The difference between the two roots of the equation 3x2+10x+c=0 is 4 2/3 . find the solutions for the equation.

x1 = - 4

x2 = 2/3

Step-by-step explanation:

Divide the equation by 3 to give

x^2 + 10x/3 + c/3 = 0

The sum of the two roots = - 10/3

So

x1 + x2 = -10/3

x1 - x2 = 4 2/3                Add these two equations.

2x1 = -10/3 + 4 2/3         Change 4 2/3 to an improper fraction

2x1 = -10/3 + 14/3            Combine the right

2x1 = 4/3                         Divide by 2

2x1/2 =4/3//2        

x1 = 2/3

x1 + x2 = - 10/3

2/3 + x2 = - 10/3

x2 = - 10/3 - 2/3

x2= -12/3

x2 = - 4

(x - 2/3)(x +4) = 0              Multiply through by 3

(3x - 2)(x + 4) =0

Check

(3x - 2)(x + 4) = 0

3x^2 + 12x - 2x - 8 =0

3x^2 + 10x - 8 = 0

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
