Solution

The correct option is B

False


We can write x28x+15x29x+18 as (x3)(x5)(x3)(x6). We did this because from the R.H.S of the give equation, we can say

we have to simplify/factorize the terms.

Can we write (x3)(x5)(x3)(x6)asx5x6?

To do that, we want x30 or x3 we can write the given expression as x5x6 if x3.

But we are not given this in the question. The given statement is not true when x = 3. So we say the statement is wrong,

because we want it to be true for all the values of x.
