​

Answer 1

Step-by-step explanation:

We have,

${x}^{2} - (2b - 1)x + ( {b}^{2} - b - 20 )= 0$

$\implies {x}^{2} - (2b - 1)x + (b - 5)(b + 4) = 0$

$\implies {x}^{2} - (b - 5)x - (b + 4)x + (b - 5)(b + 4) = 0$

$\implies \: x(x - (b - 5)) - (b + 4)(x - (b - 5)) = 0$

$\implies(x - b + 5)(x - b - 4) = 0$

$\implies \: x = b - 5 \: \: or \: \: x = b + 4$
