Question

the roots of the quadratic equations X2 +5×+6=0 are
​

Answer 1

Answer:

x = -2, -3

Step-by-step explanation:

w.k.t

$x = \frac{ - b \frac{ + }{ - } \sqrt{ {b }^{2} - 4ac} }{2a}$

$x = \frac{ - 5 \frac{ + }{ - } \sqrt{ {5}^{2} - 4(1)(6)} }{2(1)}$

$= \frac{ - 5 \frac{ + }{ - } \sqrt{25 - 24} }{2} \\ = \frac{ - 5 \frac{ + }{ - } 1}{2}$

x= (- 5 +1)/2 , ( -5 -1 )/2

= -4/2 , -6/2

= -2 , -3
