Question

Find the distance between points. x (- 3, 2) and y (1, - 2) ​

Answer 1

Distance between two points

(x2−x1)

2

+(y2−y1)

2

(x−3)

2

+(2−(−6))

2

=10

(x−3)

2

+64

=10

Squaring both sides

(x−3)

2

+64=100

x

−6x−27=0

x

2

−9x+3x−27=0

x(x−9)+3(x−9)=0

x=−3,9

Taking positive value, x=9units
