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.
is a quadratic equation for y, in terms of x.
The discriminant is -11.
x2 + 3x - 10 = (x + 5)(x - 2) ⇒ x = -5 or 2
x2+3x = 7 x2+3x-7 = 0 Using the quadratic equation formula:- x = -4.541381265 or x = 1.541381265
1,2.5
3a(3x - 2y)(3x - 2y)(3x - 2y) or 3a times (3x - 2y) to the third power
x2+3x-5 = (x+4.192582404)(x-1.192582404) factored with the help of the quadratic equation formula
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.
x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0
is a quadratic equation for y, in terms of x.
The discriminant is -11.
x2 + 3x - 10 = (x + 5)(x - 2) ⇒ x = -5 or 2
x2+3x = 7 x2+3x-7 = 0 Using the quadratic equation formula:- x = -4.541381265 or x = 1.541381265
Yes:- x2+3x+2 = 30 X2+3x+2-30 = 0 x2+3x-28 = 0 (x-4)(x+7) = 0 x = 4 or x = -7
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.
No because the discriminant is less than zero.
