Answer 1

Answer:

option d is correct

${x}^{2} - 9x + a \\ \\ where \: a = 8 \\ \\ {x}^{2} - 9x + 8 \\ \\ {x}^{2} - 8x - x + 8 \\ \\ x(x - 8) - 1(x - 8) \\ \\ (x - 1)(x - 8) \\ \\ take \\ \: x - 1 = 0 \: \: and \: \: x - 8 = 0 \\ \\ x = 1 \: \: \: \: and \: x = 8 \\ \\ hence \: the \: value \: of \: x = 1 \: and \: 8$
