Set y as zero; now you have -x2+3=0.
Multiply equation by -1; now you have x2-3=0.
Add both sides by 3; now you have x2=3.
Take the square root of both sides, and finally you have the answer, which is x=±√3.

Solve x2 plus 4x plus 3 equals 0?
x2 + 4x + 3 = 0 (x + 1)(x + 3) = 0 x ∈ {-3, -1}
Can you Solve x2 plus 13x equals -30?
x2 + 13x = -30 ∴ x2 + 13x + 30 = 0 ∴ (x + 3)(x + 10) = 0 ∴ x ∈ {-3, -10}
What is x2 plus 6x plus 9 equals x plus 3?
x2+6x+9 = x+3 x2+6x-x+9-3 = 0 x2+5x+6 = 0 Solve by factoring or with the help of the quadratic equation formula: (x+3)(x+2) = 0 Therefore: x = -3 or x = -2
How do you solve -x2 plus 2x-3?
If we assume that it equals zero and you wish to solve for x, then the answer is:-x2 + 2x - 3 = 0x2 - 2x + 3 = 0x2 -2x + 1 = -2(x - 1)2 = -2x - 1 = ± √(-2)x = 1 ± i√2
What is X2 plus 10x plus 21 equals?
x2 + 10x + 21 = (x + 3)(x + 7)
How do you solve x2 plus 3x plus 3 0?
x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
Solve x2 plus 4x plus 3 equals 0?
x2 + 4x + 3 = 0 (x + 1)(x + 3) = 0 x ∈ {-3, -1}
Can you Solve x2 plus 13x equals -30?
x2 + 13x = -30 ∴ x2 + 13x + 30 = 0 ∴ (x + 3)(x + 10) = 0 ∴ x ∈ {-3, -10}
How do you solve this problem it just says solve x2 plus 3y equals 7 3x plus y2 equals 3?
x2 + 3y = 7 3x + y2 = 3 3y = x2 + 7 y2 = -3x + 3 y = x2/3 + 7/3 y = ± √(-3x + 3) If you draw the graphs of y = x2/3 + 7/3 and y = ± √(-3x + 3) in a graphing calculator, you will see that they don't intersect, so that the system of the given equations has not a solution.
What is x2 plus 6x plus 9 equals x plus 3?
x2+6x+9 = x+3 x2+6x-x+9-3 = 0 x2+5x+6 = 0 Solve by factoring or with the help of the quadratic equation formula: (x+3)(x+2) = 0 Therefore: x = -3 or x = -2
Solve this quadratic equation x2 plus 5x plus 3 equals 0?
I suggest you use the quadratic formula. In this case, a = 1, b = 5, c = 3.
How do you solve -x2 plus 2x-3?
If we assume that it equals zero and you wish to solve for x, then the answer is:-x2 + 2x - 3 = 0x2 - 2x + 3 = 0x2 -2x + 1 = -2(x - 1)2 = -2x - 1 = ± √(-2)x = 1 ± i√2
What is X2 plus 10x plus 21 equals?
x2 + 10x + 21 = (x + 3)(x + 7)
X2 - 3 equals -3x2 plus 8x?
In general, no.
Solve x2 plus 2x - 13 equals 2?
x2 + 2x - 13 = 2 x2 + 2x - 15 = 0 (x + 5)(x - 3) = 0 x + 5 = 0 and x - 3 = 0 so x = -5 and x = 3
Solve X2 plus -2x -5.25 equals 0?
x = 7/2 and also x = -3/2 by using the quadratic equation formula.
Y equals -x2 plus 4x-3?
y = 4x-3
