Answer:
y=2 (x+6) (x+2)
Step-by-step explanation:
y = x(2x + 12) + 1(4x + 24)
factor out a 2 from the first term and a 4 from the second term
y = 2x(x+6) + 4(x+6)
now factor out the (x+6) term
y = (x+6) [2x+4]
your two terms are (x+6) and (2x+4)
the last terms can have a 2 factored out
(x+6) 2(x+2)
2 (x+6) (x+2)
