Answer:
If the equation's roots are 1 , 3, 3 then the equation can be formed by multiplying
(x -1) * ( x - 3) * (x-3) =0
x^2 -6x + 9 * (x -1) equals
x^3 -6x^2 +9x -x^2 + 6x -9 = 0 equals
x^3 -7x^2 + 15x -9 = 0
cubic equations GENERALLY have the form
ax^3 +bx^2 + cx +d = 0
Therefore
a =1 b = -7 c = 15 and d = -9
So, to make the numbers equal the equation in the problem:
x^3 + ax^2 + bx + c = 0
a = -7 b = 15 and c = -9
