To factorise x3 + 5x2 - 16x - 80 I note that -80 = 5 x -16 and 5 & -16 are the coefficients of x2 and x. Thus I have:
x3 + 5x2 - 16x - 80 = (x + 5)(x2 - 16)
and the second term is a difference of 2 squares, meaning I have:
x3 + 5x2 - 16x - 80 = (x + 5)(x + 4)(x - 4)

What is each factor as a polynomial in descending order 5x2 - 16x plus 12?
5x2 - 16x + 12 = 5x2 - 10x - 6x +12 = 5x(x - 2) - 6(x - 2) = (x - 2)(5x - 6) Whether or not these are in descending order depends on the value of x.
How do you factor 5x2 plus 3-1?
5x2 + 3x - 1 does not have rational factors.
How do you Factor 5x2-46x plus 9?
5x2-46x+9 = (5x-1)(x-9)
How do you factor 5x2 plus 20x?
5x2 + 20x = 5x (x + 4)
What is the factor of 5x2-16x plus 16?
That doesn't factor neatly. Applying the quadratic equation, we find two imaginary solutions: (8 plus or minus 4i) divided by 5x = 1.6 + 0.8ix = 1.6 - 0.8iwhere i is the square root of negative one.
