The coefficient is -3.
1 and 3
One factor is 3.

Yes. (Assuming that -3x2 is the best representation of 3x2 that this browser will allow.)
6x2 - 4x (6/2)x2 - (4/2)x = 3x2 - 2x ========
3x2 - 9x = -5; add 5 to both sides, in order to use the quadratic formula 3x2 - 9x + 5 = 0; a = 3, b = -9, and c = 5 x = [-b ± √(b2 - 4ac)]/(2a) x = {-(-9) ± √[(-9)2 - 4(3)(5)]}/[(2)(3)] = [9 ± √(81 - 60)]/6 = [9 ± √21)/6
They are multiplicands.
y2=x3+3x2
3x2 + 17x + c = 0, rearranging gives c = -3x2 - 17x
