Find all the zeros of the equation x^4-6x^2-7x-6=0

The zeros are

Step-by-step explanation:

We have been given the equation x^4-6x^2-7x-6=0

Use rational root theorem, we have

Again factor using the rational root test, we get

Using the zero product rule, we have

Therefore, the zeros are

The zeroes of   is 3,-2,    , ..

Step-by-step explanation:

Given :

To Find: Zeroes of equation

Solution:

Set x-3 =0

So, x = 3 is the first solution.

Set x+2=0

So, x =-2 is the second solution.

Now Set

Using quadratic formula :

Substitute the values a = 1 , b=1 , c=1

So,

Hence the zeroes of   is 3,-2,    , ..

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
