ANSWER

EXPLANATION
The given polynomials are:

and

We want to subtract these two polynomials.

Expand the right hand side to obtain:

Group the similar terms:

Combine the similar terms to get:

When the triangle RST is rotated by <span>90° in a clockwise direction, the name of the image after the rotation would be SRT.
The reason you get a name like this is because you're not only rotating the triangle, you also rotating the letters along with the image.</span>
