Completing the square is a method used to solve a quadratic function. This is a handy method when there are two instances of the same variable in the function.

If you aren't dealing with algebra, such as x2+3x+21, then completing the square wont be able to solve the porblem, however if you are using algebra, and you cannot factorise, then completing the square will always work

the problem is not proper to slove. I just want to suggest to follow the related link that explains the concept of completing the square clearly.

Completing the square is a method to solve quadratic equations. To use this method you take the number without a variable and subtract it from both sides, so that it is on the opposite side of the equation. Then add the square of half the coefficient of the x-term to both sides. This will give you a perfect square equation to solve for.

Yes, it won't be exact, but you can round the number to get a close estimate.

The first step would be to find the equation that you are trying to solve!

solve the equation by completing the square 2x^2+3x-2=0 (show work please!)

w^2 +/- 28w - 1 is an expression, not an equation. Expressions do not have solutions.

No because the discriminant of the given quadratic expression is less than zero.

Divide all terms by 3 so:- x2-4x = 5 Completing the square:- (x-2)2 = 9 x-2 = -/+3 x = -1 or x = 5

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

This quadratic equation has no solutions because the discriminant is less than zero.

By completing the challenge it says on it.

Four? Factoring Graphing Quadratic Equation Completing the Square There may be more, but there's at least four.

x^2-16x=-15 x^2-16x+(-8)^2=-15+(-8)^2 (x-8)^2=49 (x-8)^2=+-7 8+7=15 8=7=1 The solutions are 15 and 1. You can use the example above to solve quadratic equations by completing the square.

we alweeys add (1/2 cofftiant of x )2 (1/2*4)2 =4

Please do not remove this question from Inappropriate or split any alts from it. Thanks!

Completing the square would be the same as "Finding the square root" So an example would be 16. 16 is a perfect square so it would reduce to 4.

NO

It cannot be solved because the discriminant of the quadratic equation is less than zero

No, pi is not used to solve a square root problem.

I believe by completing the square.

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.
