(a) 3t + 15

      3(t + 5)

(b) 3a² + 9a

       3a(a+3)

(c) a²b + ab² + ab

       ab(a +b + 1)

(d) x² - 25

       x(x-25)

(e)  I'm not sure about this one, sorry

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
