x2 + 2x + 5 = 0
x2 + 2x + 5 - 5 = 0 - 5
x2 + 2x = -5
x2 + 2x + (2/2)2 = -5 + (2/2)2
x2 + 2x + 12 = -5 + 1
(x + 1)2 = -4
sq. root of (x + 1)2 = sq. root of -4
|x + 1| = 2i
x + 1 = +&- 2i
x + 1 - 1 = -1 +&- 2i
x = -1 +&- 2i
A quadratic equation
Yes it is quite possible
Completing the square is one method for solving a quadratic equation. A quadratic equation can also be solved by factoring, using the square roots or quadratic formula. Solving quadratic equations by completing the square will always work when solving quadratic equations-You can also use division or even simply take a GCF, set the quantities( ) equal to zero, and subtract or add to solve for the variable
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
Y
A quadratic equation.
A quadratic equation
By using the quadratic equation formula or by completing the square
If you mean: 11x2-34x+3 = 0 then the solutions are x = 1/11 and x = 3 by completing the square or using the quadratic equation formula
Completing the square is one method for solving a quadratic equation. A quadratic equation can also be solved by several methods including factoring, graphing, using the square roots or the quadratic formula. Completing the square will always work when solving quadratic equations and is a good tool to have. Solving a quadratic equation by completing the square is used in a lot of word problems.I want you to follow the related link that explains the concept of completing the square clearly and gives some examples. that video is from brightstorm.

it shld be on completing d 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.

This quadratic equation has no solutions because the discriminant is less than zero.
The method is called "completing the square" because it involves rearranging a quadratic equation into a perfect square trinomial. This process allows us to express the quadratic in the form ((x - p)^2 = q), where (p) and (q) are constants. By completing the square, we can easily solve for the variable and analyze the properties of the quadratic function, such as its vertex.
