Answer 2

Hi there

Here is ur answer ⤵

$\huge\mathfrak{\underline{\underline{\red {Answer }}}}$

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

$\sf \: those \: factors \: are \: \\\sf \: x =$

$\sf \frac{(2b - 1± \sqrt{ {(2b - 1)}^{2} - 4 \times ( {b}^{2} - b - 20} }{5}$

$\sf = \frac{(2b - 1)± \sqrt{ {4b}^{2} + 1 - 4b - {4b}^{2} + 4b + 80 } }{2}$

$\sf = \frac{(2b - 1)± \sqrt{81} }{2}$

$\sf \: therefore \: x = \frac{2b - 1 + 9}{2} = b + 4$

$\sf \: or \: x = \frac{2b - 1 - 9}{2} = b - 5$
