Answer:

= 2n²

Step-by-step explanation:

From the sequence 2,8,18,32,50

The difference between each numbers are

: 6, 10, 14, 18

The difference between the second sequence is 4.

Therefore the nth term of the sequence is 2n²

Answer:

2n²

Step-by-step explanation:

Since the sequence is quadratic we know this must involve an n² term

Consider each term

n = 1 → 1² = 1 → 1 × 2 = 2

n = 2 → 2² = 4 → 4 × 2 = 8

n = 3 → 3² = 9 → 9 × 2 = 18

n = 4 → 4² = 16 → 16 × 2 = 32

n = 5 → 5² = 25 → 25 × 2 = 50

n = n → n² → n² × 2 = 2n²

Thus the n th term is 2n²

Factor and add steps please<br><br> 81u^6+192
attashe74 [19]
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
