Do you need to put a plus or minus sign in front of a square root answer you get from finding the inverse of a quadratic equation?

Yes. Quite often, if you don't, you'll lose solutions. That is, the transformed equation - after taking square roots - will have less solutions than the original equation.

Is the inverse of a quadratic function is square root function?
yes
How do you formulate quadratic equation that can be solve by extracting square roots?
By using the quadratic equation formula
What are the methods use in solving quadratic equation?
By using the quadratic equation formula or by completing the square
What is the shape of a quadratic equation?
Square
How you find the solution of a quadratic equation by graphing its quadratic equation?
When you graph the quadratic equation, you have three possibilities... 1. The graph touches x-axis once. Then that quadratic equation only has one solution and you find it by finding the x-intercept. 2. The graph touches x-axis twice. Then that quadratic equation has two solutions and you also find it by finding the x-intercept 3. The graph doesn't touch the x-axis at all. Then that quadratic equation has no solutions. If you really want to find the solutions, you'll have to go to imaginary solutions, where the solutions include negative square roots.
Why do you use square roots to solve quadratic equations?
Because it's part of the quadratic equation formula in finding the roots of a quadratic equation.
What is an equation that can be used in quadratic formula completing the square and factoring?
A quadratic equation.
Can the answer to a quadratic equation be a decimal?
Yes. You can calculate the two roots of a quadratic equation by using the quadratic formula, and because there are square roots on the quadratic formula, and if the radicand is not a perfect square, so the answer to that equation has decimal.

What equation results from completing the square and then factoring?
A quadratic equation
What is the quadratic formula cannot be used to solve an equation if the coefficient of the equation x square term is?
The quadratic formula cannot be used to solve an equation if the coefficient of the equation x square term is what?
How do you solve quadratic equation by competing the square which is not a perfect square?
let, equation is ax2+bx+c=0 so, its solution will be x= (-b-sqrt(b*b-4ac))/2a x= (-b+sqrt(b*b-4ac))/2a it is generalized equation for finding roots of Quadratic eq.
What does it mean in algebra to complete the square?
A quadratic equation can be solved by completing the square which gives more information about the properties of the parabola than with the quadratic equation formula.
