Distance problem

A=(x, x)
B=(1,4)
Distance AB=√5, find x;

Correct answer:

x1 =  3
x2 =  2

Step-by-step explanation:

(x1)2+(x4)2=5  (x1)2+(x4)2=5  2x210x+12=0 2 ...  prime number 10=25 12=223 GCD(2,10,12)=2  x25x+6=0  a=1;b=5;c=6 D=b24ac=52416=1 D>0  x1,2=2ab±D=25±1 x1,2=25±1 x1,2=2.5±0.5 x1=3 x2=2  x1=3

Our quadratic equation calculator calculates it.
