$\boxed{\bold{\huge{\boxed{\sf Yes.}}}}$

Step-by-step explanation:

=> $\sf 7x+ 3 = -17-3x$

Combining like terms

=> $\sf 7x+ 3x = -17-3$

=> $\sf 10x = -20$

Dividing both sides by 10

=> $\sf x = -2$

So, -2 is a solution of the given equation.

We can split the middle term to simplify this expression.

Doing so gives us (x^2 - 4)(x^2 - 9)

Using the difference of perfect squares rule, we can simplify this even further:

(x + 2)(x - 2)(x + 3)(x - 3)

The real roots of the polynomial are:

-2, 2, -3, 3.
