If you mean 3x2-7x+x = -4 then there are no solutions because the discriminant of the quadratic equation is less than zero.
3x2 + 17x + c = 0, rearranging gives c = -3x2 - 17x
Set the equation equal to zero. 3x2 - x = -1 3x2 - x + 1 = 0 The equation is quadratic, but can not be factored. Use the quadratic equation.
3x2 = 21 describes two single values, and does not have an x intercept. 3x2 = 21 ∴ x2 = 7 ∴ x = ±√7
-3x2 + 22x = 0 You start by dividing both sides by x: ∴ -3x + 22 = 0 Then rearrange to solve for x: ∴3x = 22 ∴ x = 7 + 1/3
3x2=6+38=44
By using the quadratic equation formula which will work out as: x = 4- the square root of 32 and x = 4+the square root of 32

3x2+x-4 = 0 (3x+4)(x-1) = 0 Solutions: x = 1 and x = -4/3 By using the quadratic equation formula.
3x2 when x = 2 is the answer 3 X 4 = 12 or is the answer (3 X 2)2 = 62 = 36
3x2-9x = 0 x(3x-9) = 0 x = 0 or x = 3
Yes. (Assuming that -3x2 is the best representation of 3x2 that this browser will allow.)
