Question

X^3+15x^2+14x+210=0 factorise?
​

Answer 1

Step-by-step explanation:

x = 3.74165738677394 i

x = -3.74165738677394 i

x=-15

Answer 2

Given to factorize:-

$x^3+15x^2+14x+210=0$

Answer Keys.

• Factorization

Expressing the terms as a product.

• Common Factor

We can group the common factor.

Solution.

Let's group the terms.

• $x^3+15x^2=x^2(x+15)$
• $14x+210=14(x+15)$

Both the groups have $x+15$ as a factor.

Then,

$x^3 + 15 x^2 + 14 x + 210=(x+15)(x^2+14)$
