Find the value of a if the distance between the two points A( -3, -14)

1.	Find the value of a if the distance between the two points A( -3, -14) and B( a, -5) is 9 units
Answer» Distance= √( x2-x1)²+(y2-y1)²9=√(a+3)²+(-5+14)²9²= a²+9+6a+9²81=a²+9+6a+81a²+6a+9=0a²+3a+3a+9=0a(a+3)+3(a+3)=0(a+3)+(a+3)=0a=-3,-3 Sry I don\'t know its answer but search preksha rana channel on YouTube and like her video if u like nd share it with friends and family members
