What is the solution set to the equation x2 plus 4 equals 0?
There are no real solutions to this equation because you cannot take the square root of a negative number. However,x2 + 4 = 0x2 = -4sqrt(x2) = sqrt(-4)x = 2i, -2ihere are the imaginary solutions.
What are the solutions to the equation x2 plus 3x plus 3 equals 0?
x2 + 3x + 3 = 0 doesn't factor neatly. Applying the quadratic formula we find two imaginary solutions: (-3 plus or minus the square root of -3) divided by 2x = -1.5 + 0.8660254037844386ix = -1.5 - 0.8660254037844386iwhere i is the square root of negative 1
What is the answer to the equation x2 plus 6x plus 6 equals 0?
Using the quadratic equation formula: x = -3 - the square root of 3 or x = -3 + the square root of 3
What is the double solution for x2-4x plus a?
-2
The x intercepts of y equals x2-2?

Is it possible to have a square root as a solution to a quadratic equation?
Yes. For example, the equation x2 = 2, which in standard form is x2 - 2 = 0, has the two solutions x = square root of 2, and x = minus square root of 2.
What are the solutions to the equation x2 plus 3x plus 3 equals 0?
x2 + 3x + 3 = 0 doesn't factor neatly. Applying the quadratic formula we find two imaginary solutions: (-3 plus or minus the square root of -3) divided by 2x = -1.5 + 0.8660254037844386ix = -1.5 - 0.8660254037844386iwhere i is the square root of negative 1
One of the roots of the equation x2 plus 3x - 18 equals 0 is 3 what is the other root?
x2 + 3x - 18 = 0 (x - 3)(x + 6) = 0 x = 3 or -6
What is the answer to the equation x2 plus 6x plus 6 equals 0?
Using the quadratic equation formula: x = -3 - the square root of 3 or x = -3 + the square root of 3
X2 plus 11x plus 11 equals 7x plus 9?
X2+11x+11 = 7x+9 X2+11x-7x+11-9 = 0 x2+4x+2 = 0 Solve as a quadratic equation by using the quadratic equation formula or by completing the square: x = -2 + or - the square root of 2
What is the solution to the following equation x2 plus 3x plus 7 equals 0?
x^2 + 3x +7 = 0 doesn't factor neatly. Applying the quadratic equation, we find two imaginary solutions: (-3 plus or minus the square root of -19) divided by 2x = -1.5 + 2.179449471770337ix = -1.5 - 2.179449471770337iwhere i is the square root of negative 1
What is the determinant of a quadratic function?
It is the equation inside the square root of the Quadratic FormulaIf > 0 there is a solutionIf < 0 there is no solutionBecause you can not calculate the Square Root of a Negative Number
What is the double solution for x2-4x plus a?
-2
The x intercepts of y equals x2-2?
4
Which equation has roots of 3and 5?
x2 - 2x - 15 = 0
How many solutions to x2-10 equals 0?
x2-10 = 0 x2 = 10 x = the square root of 10
