If you meant 3x2 - 5x + 2, here is your answer 3x2 - 5x +2 = 0 => 3x2 - 3x - 2x + 2 = 0 => 3x(x-1) - 2(x-1) = 0 => (3x - 2) (x-1) = 0 => x = 2/3 or, x = 1
21x3-35x2+14x = 7x(3x2-5x+2)
Quotient: 2x+3 Remaider: 2
2x2 + (5x-4x)2 + (x-x)2 = 2x2 + x2 + 02 = 2x2 + x2 = 3x2
(3x2 + 2x + 1)
3x2 + 5x + 2 is a quadratic expression that can be factored as follows: 3x2 + 5x + 2 = 3x2 + 3x + 2x + 2 = 3x(x + 1) + 2(x + 1) = (3x + 2)(x + 1)
f(x) = 3x2 + 5x + 2fprime(x) = 6x + 5

21x3-35x2+14x = 7x(3x2-5x+2)
If the original is 2x + 3x2 + 6 + 5x3, you should rearrange the terms in order of exponent:5x3 + 3x2 + 2x + 6
Quotient: 2x+3 Remaider: 2
3x2 - 5x - 2 can be factored into (3x + 1) (x - 2)
2x2 + (5x-4x)2 + (x-x)2 = 2x2 + x2 + 02 = 2x2 + x2 = 3x2
Dividend: 4x^4 -x^2 +17x^2 +11x +4 Divisor: 4x +3 Quotient: x^3 -x^2 +5x -1 Remainder: 7
3x2 + 15x + 6 = 3*(x2 + 5x + 2). There are no further rational factors.
