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)

Answer:
S = 3.92π
Step-by-step explanation:
The formula for area of a sector is
S = (Ф/360°)πr² where Ф is the angle of the sector in degrees, and r is the radius.
The radius is half of the diameter, so we have 5 = 5.6/2 = 2.8, and Ф = 180°
The area is
S = (180°/360°)π(2.8)²
S = (1/2)π(7.84)
S = 3.92π
If A = {1, 3, 5, 15}, B = {2, 3, 5, 7}, C = {2, 4, 6, 8} Then what is (A U B) ∩ C?

Answer:
Step-by-step explanation:
Given
Required
Determine (A U B) ∩ C
First, we calculate A u B
This means that we bring A and B together without repetition.
Next:
This means that we only get the common items
