Question

in polynomial if situation is 1(a⁴+a³-1) what will happen or what will answer if answer will be a³ + a² - 1 so why it is like that why power deduct explain for brilliant​

Answer 1

Answer:

a³- 1/a³ = 60

given,

a-1/a = 4

squaring both side

(a-1/a)² = 4²

a²+1/a²-2(a) (1/a) = 16

a²+1/a²-2=16

a²+1/a²=16+2

a²+1/a²= 18

a³-b³=(a-b) (a²+b²+ab)

a³-1/a³=(a-1/a) (a²+1/a²+a×1/a)

=4(14+1)

=4×15

=60

Answer 2

Answer:

Step-by-step explanation:a-1/a=4square on both sides (a-1/a)²=4²a²+1/a²-2a.1/a=16a²+1/a²-2=16a
