Find all roots x^3 + 7x^2 + 12x = 0

Therefore the THREE roots are

Step-by-step explanation:

Given:

To Find:

All  the Roots = ?

Solution:

As the degree of the polynomial is THREE then the number of root are also THREE.

Now one root is Zero For other we need to Factorize

So by Splitting the middle term

i.e Factor of 12 such that sum should be 7

i.e 3 × 4 = 12  and 3 + 4 = 7

∴

Therefore the THREE roots are
