2 • (6x2 - 3x - 2)
Step by step solution :
Step 1 :
Equation at the end of step 1 :
((22•3x2) - 6x) - 4
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
12x2 - 6x - 4 = 2 • (6x2 - 3x - 2)
Trying to factor by splitting the middle term
3.2 Factoring 6x2 - 3x - 2
The first term is, 6x2 its coefficient is 6 .
The middle term is, -3x its coefficient is -3 .
The last term, "the constant", is -2
Step-1 : Multiply the coefficient of the first term by the constant 6 • -2 = -12
Step-2 : Find two factors of -12 whose sum equals the coefficient of the middle term, which is -3 .
-12 + 1 = -11
-6 + 2 = -4
-4 + 3 = -1
-3 + 4 = 1
-2 + 6 = 4
-1 + 12 = 11
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
2 • (6x2 - 3x - 2)
Hope this helped!

Answer:
m = (y2 - y1) / (x2 - x1) = (10 - 6) / (3 - 1) = 2 slope of line
y = m x + b standard form of straight line
y = 2 x + b where b is the intercept at x = 0
b = y - 2 x
b = 6 - 2 = 4 from our first equation
Also, b = 10 - 6 = 4 check from second equation
y = 2 x + 4 is our equation
Check if y = 6 and x = 1 then
y = 2 * 1 + 4 = 6 verifying the first point given
multiply the tops and bottoms, so:
1 * -5 * 3 = -15 for top
and
5 * 7 * 4 = 140 for bottom
then reduce by dividing by 5, and you get:
-3/28

Answer:
the solid color fleece is a better price
Step-by-step explanation:
Data:
Solid color fleece: S
Paterned fleece : P
Cost:
S=$1649 per 6 yards
P= $15.40 per 16 feet
To find which fleece is better price you need to find the price of each one per the same unit.
1. Turn the yards in feet (1 yd is equal to 3 feet )
2. Find the price per 1 feet of each fleece:
Solid color fleece: $ 0.916 per 1 feet
Patterned fleece: $0.9625 per 1 feet
Then, the solid color fleece is a better price
