Question

if the distance between (2, -2) and (-1,x) is 5 units then one of the value of x is​

Answer 1

X can be either (-7) or 3

Answer 2

Answer:

Step-by-step explanation:

By using distance formula,

or,     5=$\sqrt{(-1-2)^2+(x-(-2)^2)$

or,     5=$\sqrt{(-3)^2+(x-2)^2$

Squaring on both sides, we get

or,     25=9+x^2-4x +4

or,     $x^{2}$-4x -12=0

or,    $x^{2}$-6x+2x-12

or,    x(x-6)+2(x-6)

or,     (x+2) (x-6)
