a

r  =  a2 + 12a       Factor an  a  out of both terms on the right side.

r  =  a(a + 12)

b

s  =  b2 - 8b + 7

s  =  b2 - 8b + 7       What two numbers that add to  -8  and multiply to  7 ?    -7  and  -1

So the right side factors like this...

s  =  (b - 7)(b - 1)

c

t  =  c2 - c - 30

t  =  c2 - 1c - 30          What two numbers add to  -1  and multiply to  -30 ?   +5  and  -6  . So....

t  =  (c + 5)(c - 6)

d

u  =  d2 + 6d - 7

u  =  d2 + 6d - 7        What two numbers add to  6  and multiply to  -7 ?   +7  and  -1  . So...

u  =  (d + 7)(d - 1)
