@ashen monolith you could just substitute values 0, 3, and -1.5 and get simultaneous equations

#

Or you could write the equation in the form a(x-b)(x-c) where b and c are the roots and then expand

#

I did that

#

Well maybe not with a

#

But simialr

#

But the method was not convincing

#

Yes you cant leave out the a with that method

#

You need to substitute 0 and work it out

#

a(-9/2) = -9
a = 2
