the correct option is 2.
according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.
it is given that triangles abd, cad, and cba are similar.
two triangles are similar if their corresponding sides are proportional.
in triangle cba, using pythagoras theorem
triangle abd and cba are similar,
triangle cad and cba are similar,
using (1), (2) and (3), we get
therefore option 2 is correct.

Given given expression to calculate is:
We have to add both the polynomials
Addition of two polynomials involves combining like terms present in the two polynomials
We have to add like terms
Like terms means "the terms having same variable and same exponent"
And we have to add the constants
Thus the polynomials are added
