Question

the distance btween the point (3,1)and(0,x)is 5units find x​

Answer 1

Answer:

x= 5 & (-3)

Step-by-step explanation:

5=√(3-0)² +(1-x)²

5=√3²+(x²+1-2x)

5=√9+x²+1-2x

5=√10+x²-2x

on squaring both side,we get

25=x²-2x+10

15=x²-2x

x²-2x-15=0

x²-5x+3x-15=0

x(x-5)+3(x-5)=0

(x-5)(X+3)=0

therefore x=5 & (-3)
