factor completely 9x4 + 12x3 + 21x2.

3(3x4 + 4x3 + 7x2)
3x(3x3 + 4x2 + 7x)
3x2(3x2 + 4x + 7)
prime

The factor of

Solution:

From question given that the equation is

We have to find the factors of the given equation.

By taking 3 as a common term in above expression,

By taking “x” as a common term in above expression, we get equation as

Again taking “x” as a common term in above expression, we get

cannot be factorized.(imaginary roots)

Hence factor of

3x2(3x2 + 4x + 7)
