Example 15 For which values of p does the pair of equations given below has unique solution? 4x + py + 8 =0 2x + 2y + 2 = 0 4x + py + 8 = 0 2x + 2y + 2 = 0 So, a1 = 4 , b1 = p , c1 = 8 & a2 = 2 , b2 = 2 , c2 = 2 Given that equations has unique number of solutions 1/ 2 1/ 2 4/2 /2 /2 " " 4/2 " " 4/2 2 p " " 4 So, for all values of p except 4, We will have a unique solution for the given set of questions
