Answer 2

Answer:

x = 1 is a solution of x2 + kx + 3 = 0, which means it must satisfy the equation. (1)2 + k(1) + 3 = 0 k = -4 Hence the required value of k = -4 Find other root: We have equation, x2 – 4x + 3 = 0 x2 – x – 3x + 3 = 0 x(x – 1) – 3(x – 1) = 0 (x – 1)(x – 3) = 0 either x – 1 = 0 or x – 3 = 3 x = 1 or x = 3 Other root is 3
