5x(x^4+7x+4)
35x2 - 38x + 8
21x3-35x2+14x = 7x(3x2-5x+2)
It is the same as: 9+20x+20 = 20x+29
4x2+20x+25 (2x+5)^2
(7x - 5)(5x - 2)
-(5x + 3)(7x - 2)
7x(3x3 - 2x2 + 5x + 1)
It is: 4x -34x^2 -21 simplified
(5x - 3)(7x + 9)
15x4 and 35x2 = 5x2
A trinomial.
Combine all lie term: x + x - 22x = -20x 2 + 1 = 3 So the answer is -20x +3 or 3 - 20x
