The solution set of the following equation 1/5x^2 = x -4/5 is {1, 4}

1/5x^2 = x -4/5

x^2 = 5x - 4

x^2 - 5x + 4 = 0

(x - 1)(x - 4) = 0

x =1 or x = 4

1/5x^2 = x -4/5

x^2 = 5x - 4

x^2 - 5x + 4 = 0

(x - 1)(x - 4) = 0

x =1 or x = 4

(x + 5)(x - 2) = 18

x^2 + 3x - 10 = 18

x^2 + 3x - 28 = 0

(x + 7)(x - 4) = 0

x + 7 = 0 or x - 4 = 0

x^2 + 3x - 10 = 18

x^2 + 3x - 28 = 0

(x + 7)(x - 4) = 0

x + 7 = 0 or x - 4 = 0
