Question

find the nature of the roots of x square + 7 x + 6 is​

Answer 1

Answer:

6 is the correct answer

Answer 2

SOLUTION:-

Given

• Quadratic equation x²+7x+6

To Calculate

• Nature of the roots

Explanation

Quadratic equation x²+7x+6 [Given]

This is of the form ax²+bx+c=0

Where,

a = 1

b = 7

c = 6

We know that,

☆ D = (b²-4ac) ☆

Putting values,

➡️ D= 7²-4×1×6

➡️ D = 49-24

➡️ D= 25

D > 0

Hence,

• The Given equation has Real and unequal roots.

________________________________

☃️ Additional information ☃️

Case1

When D>0

In this case , The roots are real and distinct

Case2

When D=0

In this Case , The roots are real and equal

Case3

When D<0

In this case, No real Roots
