The value of x is equal to -5/6
To solve this question, we have to add two polynomials together. The polynomials are;
This involves adding of two or more different polynomials together. The polynomials adding together are or must be of the same degree. i.e x^2 must add to another coefficient of x^2 and x^3 adds to another coefficient of x^3 and so on.
In this given question, let's add the polynomials together.
Now, let's equate this with the last polynomial given
Let's solve for x
The value of x is equal to -5/6
