Find the point on x-axis which is equidistant from the points (2.-2) and (-4.2) |
|
Answer» <P>Step-by-step explanation: Let the point on the x−axis be P(a,0) Let the other two point be A(−2,5) and B(2,−3) So by distance FORMULA we have, Distance between two POINTS = (x2−x1)2+(y2−y1)2 Then, PA=PB PA2=PB2 ⇒(a+2)2+(0−5)2=(a−2)2+(0+3)2 ⇒a2+4+4a+25=a2+4−4a+9 ⇒4a+29=−4a+13 ⇒ 8a=−16⇒a=−2 |
