Answer 2

QUESTION⤵️

${x}^{2} - 4x - 5 = 0$

ANSWER⤵️

MIDDLE TERM SPLITTING IS NOT POSSIBLE HERE,

FORMULA USED:::-

$x = \frac{ - b \: plus \: minus \sqrt{ {b}^{2} - 4ac} }{2a}$

LET'S DO IT:::-

PUTTING THE VALUES

a= 1

b= -4

c= -5

$x = \frac{ - ( - 4) \: plus \: minus \sqrt{ {( - 4)}^{2} - 4 \times 1 \times ( - 5) } }{2 \times 1}$

$x = \frac{4 \: plus \: minus \: 6}{2}$

$x = \frac{4 + 6}{2} \: and \: x \: = \frac{4 - 6}{2}$

$x = 5 \: and \: x = - 1$
