How Do You Complete The Square Of An Equation

How Do You Complete The Square Of An Equation - Figure 1 Step two requires that you add (b/2)^2 to both sides and it should be clear that, in this example, b equals -6. So to find the value of (b/2)^2, just plug in -6 for be and solve as follows: In this case, (b/2)^2 equals 9 Since (b/2)^2 equals 9, go ahead and add 9 to both sides of the equals sign as follows: X 2 10 x 24 We complete the square by taking half of the coefficient of our x term squaring it and adding it to both sides of the equation Since the coefficient of our x term is 10 half of it would be 5 and squaring it gives us 25 x 2 10 x 25 24 25 We can now rewrite the left side of the equation as a squared term

How Do You Complete The Square Of An Equation

We can use a method called completing the square. Let's start with the solution and then review it more closely. ( 1) x 2 + 6 x = − 2 ( 2) x 2 + 6 x + 9 = 7 Add 9, completing the square. ( 3) ( x + 3) 2 = 7 Factor the expression on the left. ( 4) ( x + 3) 2 = ± 7 Take the square root. ( 5) x + 3 = ± 7 ( 6) x = ± 7 − 3 Subtract 3. Courses on Khan Academy are always 100% free.

How Do You Complete The Square Of An EquationStep 1: Write the quadratic equation as x 2 + bx + c. ( Coefficient of x 2 needs to be 1. If not, take it as the common factor.) Step 2: Determine half of the coefficient of x. Step 3: Take the square of the number obtained in step 1. To do this you will subtract 8 from both sides to get 3x 2 6x 15 Next you want to get rid of the coefficient before x 2 a because it won t always be a perfect square Because there is a 3 in front of x 2 you will divide both sides by 3 to get x 2 2x 5
