This is only half of an equation.
If -x^2 + 3x +2y = 0, then x^2 -3x = 2y and y = (x^2-3x)/2
Solving for x is the inverse, but difficult without a second equation.

What is the graph of the equation 2x2-6x plus 2y plus 18 equals 0?
2x2-6x+2y+18 = 0. Subtract the 2y from both sides. 2x2-6x+18 = -2y. Divide all by -2 to get y by itself. -x2+3x-9 = y. This graph is going to be a parabola that opens downward, like a frown.
Y equals x2 plus 3x plus 2?
is a quadratic equation for y, in terms of x.
What is the discriminant for this equation x2-3x plus 5 equals 0?
The discriminant is -11.
What is the solution of this quadratic equation x2 plus 3x-10 equals 0?
x2 + 3x - 10 = (x + 5)(x - 2) ⇒ x = -5 or 2
What number is x when x squared plus 3x equals 7?
x2+3x = 7 x2+3x-7 = 0 Using the quadratic equation formula:- x = -4.541381265 or x = 1.541381265
Which two values of x are roots of the polynomial x2 plus 3x - 5?
x2 + 3x - 5 is an expression, not an equation. An equation may have roots, an expression does not. However, x2 + 3x - 5 = 0 is an equation and its roots are -4.1926 and 1.1926 (approx).
What is the solution of the quadratic equation x2 plus 3x-10?
1,2.5
How do you factor x2 plus 3x-5?
x2+3x-5 = (x+4.192582404)(x-1.192582404) factored with the help of the quadratic equation formula
Can anyone help you factor 81ax3-162ax2y plus 108axy2-24ay3?
3a(3x - 2y)(3x - 2y)(3x - 2y) or 3a times (3x - 2y) to the third power
What is the graph of the equation 2x2-6x plus 2y plus 18 equals 0?
2x2-6x+2y+18 = 0. Subtract the 2y from both sides. 2x2-6x+18 = -2y. Divide all by -2 to get y by itself. -x2+3x-9 = y. This graph is going to be a parabola that opens downward, like a frown.
Can you put the equation x2 - 5 -4x2 plus 3x equals 0 in the form ax2 plus bx plus c equals 0?
x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0

What number is x when x squared plus 3x equals 7?
x2+3x = 7 x2+3x-7 = 0 Using the quadratic equation formula:- x = -4.541381265 or x = 1.541381265
Would x2 plus 3x plus 2 equals 30 be considered a quadratic equation although 'y' doesn't equal '0'?
Yes:- x2+3x+2 = 30 X2+3x+2-30 = 0 x2+3x-28 = 0 (x-4)(x+7) = 0 x = 4 or x = -7
Put the equation ''x2 plus 3x plus 7 equals 9 into the quadratic formula?
First you must put everything to the left side, leaving only zero on the right. The original equation is: x2 + 3x + 7 = 9 Subtract 9 on each side: x2 + 3x - 2 = 0 This is the same as: 1x2 + 3x - 2 = 0 Therefore, the coefficients are: a = 1, b = 3, c = -2. Replace these in the quadratic equation.
