1. Given s = 3x +t/r rearrange the equation for x, in terms of r, s, and t
2. Given 5ax + b = C, rearrange the equation for x, in terms of a, b, and c.

Step-by-step explanation:

1). s =

   r.(s) =

   rs = 3x + t

   rs - t = 3x

2). 5ax + b = c

   (5ax + b) - b = c - b

   5ax = c - b

    x =

The factored form of given polynomial is

Step-by-step explanation:

Given the polynomial

We have to factor the above polynomial completely.

Take common from each term.

Here, the quadratic polynomial is prime i.e it cannot be factored into lower degree polynomial. It has complex roots.

Hence, the factored form of given polynomial is
