Step-by-step explanation:
Use a version of the AC Method.
A
=
3
, B
=5
, C
=
12
Since the sign on the constant term is −
, look for a pair of factors of A
C
=
36 whose difference is B
=
5
The pair 4
, 9 works.
Now use that pair to split the middle term, then factor by grouping:
3
x
2
+
5
x
−
12 =
3
x
−
4
x
+
9
x
−
12
=
(
3
x
2
−
4
x
)
+
(

) =
x (
3
x
−
4
)
+
3
(

x
−
4
)
Answer:
algabraic
Step-by-step explanation:
-6(1-5x)=54
First you will distribute the -6 into the parentheses giving you
-6+30x=54 remember that a negative times a negative equals a positive
Now you add 6 to 54 this cancels out your -6
30x=60
Now divide 30x by 30 and 60 by 30 giving you <u>x=2</u>
8=8x-4(x+8)
first distribute -4 into the parentheses giving you
8=8x-4x-32
Now to simplify put the 8x and- 4x together, then add 32 to the 8 on the other side giving you
40=4x
Now divide 40 by 4 which will give you <u>10=x or x=10</u>
