Answer:
Steps to Construct a Perpendicular Bisector of line segment are as follows:
Step 1 : Draw the line segment of given
length or any length.
Step 2 : With W as center, using compass, draw a circle ( or two
arcs one above line and one below line ) . The radius of
circle ( or arcs ) should be more than half the length of
.
Step 3 : With the same radius and with X as center, draw
another circle (or arcs) using compass. Let it cut the
previous circle (or arcs) at A and B.
Step 4 : Join . It cuts at O.
Therefore, is perpendicular bisector of

Answer:
2 ± √3
Step-by-step explanation:
<h3>Solving quadratic equation by completing squares: </h3>
x² - 4x = -1
- Divide the coefficient of x by 2.
4 ÷ 2 = 2
- Now, square the result and add that to both sides of the equation.
2² = 2* 2 = 4
x² - 4x + 4 = -1 + 4
x² - 4x + 4 = 3
x² - 2 * x * 2 + 2² = 3
- Compare it with a² - 2ab + b² . Now , a = x and b = 2
(x - 2)² = 3
- Take square root both sides
x - 2 = ±√3
x = 2 ± √3
<h3>Solutions: x = 2 +√3 ; 2 - √3</h3>
