Answer:
(2x+1) (2x-7)
Step-by-step explanation:
Multiply the coefficient of the first term by the constant 4 • -7 = -28
Find two factors of -28 whose sum equals the coefficient of the middle term, which is -12
( -28 + 1 = -27
-14 + 2 = -12 )
Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -14 and 2
4x2 - 14x + 2x - 7
Add up the first 2 terms, pulling out like factors :
2x • (2x-7)
Add up the last 2 terms, pulling out common factors :
1 • (2x-7)
Add up the four terms :
(2x+1) • (2x-7)

Answer:
D. 1/44
Step-by-step explanation:
divide both sides by the # in front of X - in this case its 6. you should get x= 3/22 ÷ 6 and get your answer there by plugging in the calculator. or on paper-
do 3/22 × 1/6 which is also reduced to --> 1/22 × 1/2 and that is 1/44 but you should be able to jist plug 3/22÷ 6 in if you take middle/highschool math anyways
