ANSWER : (9u - 8)2
STEPS:
Step-1 : Multiply the coefficient of the first term by the constant 81 • 64 = 5184
Step-2 : Find two factors of 5184 whose sum equals the coefficient of the middle term, which is -144 .
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -72 and -72
81u2 - 72u - 72u - 64
Step-4 : Add up the first 2 terms, pulling out like factors :
9u • (9u-8)
Step-5 : Add up the four terms of step 4 :
(9u-8) • (9u-8)
Which is the desired factorization
Answer:
c
Step-by-step explanation:
Solve for y,
13x - 11 y = -12
13x + 12 = 11y
Answer: y = (13/11) x + (12/11)
Answer:
3 1/6
Step-by-step explanation:
2 1/2 + 2/3 = 2 3/6 + 4/6. add 3 and 4, you get 2 7/6. simplify by taking 6 from 7 and add 1 to 2. that leaves you with the answer
4/6 = x + 3/ 12 - x
4( 12 - x) = 6( x + 3)
48 - 4x = 6x + 18
-4x - 6x = 18 - 48
- 10x = -30
x = 3
