4x^2 - 25 = 0

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

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

6x^2 = 13x + 5

6x^2 - 13x - 5 = 0

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

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

the solution set for the equation 6x^2 = 13x + 5 is {-1/3, 5/2}

6x^2 - 13x - 5 = 0

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

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

the solution set for the equation 6x^2 = 13x + 5 is {-1/3, 5/2}
