Find all positive integer values of c such that the equation x^2 - 11x + c = 0 only has roots that are real and rational. Express them in decreasing order, separated by commas.
Find all positive integer values of c such that the equation x^2 - 11x + c = 0 only has roots that are real and rational. Express them in decreasing order, separated by commas.
x2 – 11x + c = 0
(x – 5)(x – 6) = 0 x = 5, x = 6 —>> c = 30
(x – 4)(x – 7) = 0 x = 4, x = 7 —>> c = 28
(x – 3)(x – 8) = 0 x = 3, x = 8 —>> c = 24
(x – 2)(x – 9) = 0 x = 2, x = 9 —>> c = 18
(x – 1)(x – 10) = 0 x = 1, x = 10 —>> c = 10
