Is \(\sqrt{6a + x^2} = a + x\)?

(1) x = 0

(2) a = 2

hi

The way I approached the DS is as under...

if both statements, taken together, the equation is clearly solvable...

however, to check whether any single value can solve the DS - as very often it can - it is very essential to simplify the question stem

After simplification, the stem looks like as under:

6a - a^2 = 2ax

here it is very clear that neither "a" nor "x" got cancelled out, so the magnitudes of 2 variables both are required to solve the DS...

please say to me whether the process I have followed is okay ...

thanks in advance ...
