Question

find the discriminant of the following equation
x2+5x-6=0​

Answer 1

Step-by-step explanation:

Here is the answer

Given Equation =>

\bf{x {}^{2} + 5x + 6 = 0}x

2

+5x+6=0

Comparing the given Equation with ax^2 + bx + c = 0

We get,

a = 1

b = 5

c = 6

\bf{ \triangle = {b}^{2} - 4ac}△=b

2

−4ac

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

2

−4×1×6

\bf{= 25 - 24 = 1}=25−24=1

Thus,

\bf {\triangle \: = 1}△=1

The value of discriminant is 1.
