3x2 - 15x + 42 = 3*(x2 - 5x + 14) which cannot be factorised further.
-3(x - 3)(x + 1)(x + 1)
2x4 - 9x3 + 13x2 - 15x + 9 = 2x4 - 6x3 - 3x3 + 9x2 + 4x2 - 12x - 3x + 9 = 2x3(x - 3) - 3x2(x - 3) + 4x(x - 3) - 3(x - 3) = (x - 3)*(2x3 - 3x2 + 4x - 3) So the quotient is (2x3 - 3x2 + 4x - 3) and the remainder is 0.
the answer is 3x2
3x2 + 15x + 6 = 3*(x2 + 5x + 2). There are no further rational factors.
3x2 - 15x + 42 = 3*(x2 - 5x + 14) which cannot be factorised further.

96= 48x2 48= 24x2 24= 12x2 12= 6x2 6= 3x2 Thus 96= 2x2x2x2x3
3x2 = 15x 3x2 - 15x = 0 x(3x - 15) = 0 x = 5 Check it. 3 x 25 = 75 15 x 5 = 75 It checks.
3x2-9x-30 =3x2+6x-15x-30 =3x(x+2)-15(x+2) =(3x-15)(x+2) OR 3(x - 5)(x+2)
-3(x - 3)(x + 1)(x + 1)
2x4 - 9x3 + 13x2 - 15x + 9 = 2x4 - 6x3 - 3x3 + 9x2 + 4x2 - 12x - 3x + 9 = 2x3(x - 3) - 3x2(x - 3) + 4x(x - 3) - 3(x - 3) = (x - 3)*(2x3 - 3x2 + 4x - 3) So the quotient is (2x3 - 3x2 + 4x - 3) and the remainder is 0.
It is a second degree polynomial.
If you mean 3x2+4x-2 = 0 then it can be solved by means of the quadratic equation formulla
If it is one like below: 8-3x2/156-155x3+4/5589x12 then, I would suggesting using the acronym, PEMDAS Parentheses Exponents Multiplication Division Addition Subtraction It also depends what kind of math problem you are trying to solve If you have any other math problems that I could not answer here, I would suggest contacting your math teacher or someone in your family or one of your friends that are good with math.
