When a = 1 1/2 = 3/2,

\(2a = 3\\ 2a - 3 = 0\)

\((5a^2-13a+4)(2a - 3) = (5a^2-13a+4)(0) = 0\)

To evaluate this expression, let's first start with 2a-3. We know a = 3/2. Thus, 2a - 3 is 3 - 3 which is 0. We know anything times 0 is 0 so...

...the answer is 0!!

0!! Is the double factorial of zero (0), and that equals one (1)

0!! =1

Are saying the answer is one (1), or are you related to Mr. !!!BB?

Hi Hypotenuisance,

What guest is telling you is that the exclamation mark ! has a mathematical meaning of its own.

So do not use it the way that you just did.
