Question

Find the discriminant of the following equation:

x²+5x-6=0

1

48

-38

49

​

Answer 1

Answer:

we know D=(b²-4ac)

Step-by-step explanation:

D=(5²-4*-6*1)=√(25+24)=49 is answer

Answer 2

Step-by-step explanation:

compare above equation by

$a {x}^{2} + bx + c = 0$

we have

a = 1 , b = 5, c = -6

then discriminant

D = b^2 - 4ac

$= ( {5})^{2} - 4 \times 1 \times ( - 6)$

= 25 +24

= 49
