P(x) =2x3 -11x2 -4x +1 g(x) =2x +1
icang [17]

Answer:

see explanation

Step-by-step explanation:

If (2x + 1) is a factor then x = - \frac{1}{2} is a root and P(- \frac{1}{2} ) = 0 ← Factor theorem

P(- \frac{1}{2} )

= 2(- \frac{1}{2} )³ - 11(- \frac{1}{2} )² - 4(- \frac{1}{2} ) + 1

= - \frac{1}{4} - \frac{11}{4} + 2 + 1

= - \frac{12}{4} + 3

= - 3 + 3

= 0

Since P(- \frac{1}{2} ) = 0 then g(x) is a factor of P(x)

Somebody please help meeeee pt.2​
rosijanka [135]

Answer:

See explanation

Step-by-step explanation:

Consider the sequence 10, 6, 2, -2, -4, ...

Rewrite it as

a_1=10,\\ \\a_2=6,\\ \\a_3=2,\\ \\a_4=-2,\\ \\a_5=-6,...

The points on the coordinate plane are

(1,a_1),\ (2,a_2),\ (3,a_3),\ (4,a_4),\ (5,a_5),... (see attached graph).

Since

4=a_2-a_1=a_3-a_2=a_4-a_3=a_5-a_4=..., given sequence is arithmetic.
