Answer» This implies thatx2+2ax=4x−4a−13orx2+2ax−4x+4a+13=0orx2+(2a−4)x+(4a+13)=0Since the equation has just one SOLUTION INSTEAD of the usual TWO distinct SOLUTIONS, then the two solutions MUST be same i.e. discriminant = 0.Hence we get that(2a−4)2=4⋅1⋅(4a+13)or4a2−16a+16=16a+52or4a2−32a−36=0ora2−8a−9=0or(a−9)(a+1)=0So the values of a are −1 and 9. |
