Question

(5)Divide the first polynomial by the second polynomial and find the remainder using remainder theorem.
(ii) (2x3 - 2x2 + ax – a) ; (x – a)
PLEASE ANSWER THIS ​

Answer 1

$\large\boxed{\rm{\blue{★ﾑɳรωεя★\leadsto}}}$

$\sf{p(x) = 2x3 – 2x2 + ax – a}$

$\sf{Divisor = x – a}$

$\sf{∴ take ~x = a}$

By remainder theorem,

$\sf{Remainder = p(a)}$

$\sf{p(x) = 2x3 – 2x2 + ax – a}$

$\sf{∴ p(a) = 2a3 – 2a2 + a(a) – a}$

$\sf{= 2a3 – 2a2 + a2 – a}$

$\sf{∴ Remainder = 2a3 – a2 – a}$

Answer 2

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
