3x^2 -14x +15 = (3x-5)(x-3)
3x2 -14x -24 can be factored as (3x + 4)(x - 6).
(2x+3)(2x+4)
if you mean (3/(2x-5))(21/(8x2-14x-15)) you would get (63/( (2x-5)(4x+3)(2x-5) ) simplified more would be 63/ ( (2x-5)2(4x+3) )
yes, and it is 14x
3x^2 -14x +15 = (3x-5)(x-3)
14x squared minus 7x to the 3rd power can be factored to 7x2(2-x).
3x2 -14x -24 can be factored as (3x + 4)(x - 6).
21x3-35x2+14x = 7x(3x2-5x+2)
14x2-7x2-16 7x2-16 (this can't be simplified any more)
2x(8x-7)
14x2 - 39x - 35 = (7x + 5)(2x - 7)
I suppose that would be 14x2 - 7x3. Just take out the common factor, 7x2. Divide each term by this factor to find the other factor.
7(x - 1)(x + 3)
(x - 16)(x + 2) x = 16 or -2
Yes because if x2-14x+49 then it is (x-7)(x-7) when factored
The polynomial IS written in descending order.
