Factor the polynomial. 3x^4 +6x^3 + 9x^2

3 x^2 (x^2 + 2 x + 3)

Step-by-step explanation:

Factor the following:

3 x^4 + 6 x^3 + 9 x^2

Hint: | Factor common terms out of 3 x^4 + 6 x^3 + 9 x^2.

Factor 3 x^2 out of 3 x^4 + 6 x^3 + 9 x^2:

 3 x^2 (x^2 + 2 x + 3)

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32
