Factor 5x
– 28x – 12.
Here, a = 5, b = –28 and c = –12.
ac = 5(–12) = –60
Find two factors of –60 whose sum is –28.
–30(2) = –60 and –30 + 2 = –28
Write –28x as –30x + 2x.
Factor 5x from the first two terms and 2 from the last two terms.
Factor x – 6 from the two terms.
Therefore,
37.
SOLUTION:
Factor out the GCF, 12x.
