Question

Write the discriminant of the given quadratic equation x² + x - 12 = 0​.

Answer 1

Step-by-step explanation:

Here, a=1. ,b=1 ,c= -12

D (discriminant) = b^2 -4ac

= (1)^2 -4+1* (-12)

=1+48

=49

Answer 2

Yo!

Here's the answer✨

To find: Discriminant of the quadratic equation:

Formula to be used : b²- 4ac.

The equation given in the question can be related to:

ax²+bx+c

Therefore comparing the two,we get:-

a= 1.

b= 1.

c= -12.

Now substituting the values in the Discriminant formula we get,

(1)²- 4×1×-12= 0

•°• 1+48

= 49 is the answer!

Hope it helps <3
