Question

Find the remainder when
3x3 - 2x + 5 is divided by x + 2.
​

Answer 1

Answer:

the remainder when $3x^3-2x+5$ divided by x+2  is (-15)

Step-by-step explanation:

given,

$3x^3-2x+5$ divided by x+2

we need to find the remainder ;

$3x^3-2x+5$  ÷ (x+2)

the above equation can be written as :

$3x^3-2x+5$  ÷ (x+2) = $(3x^2-6x+10)(x+2) + (-15)$

⇒ $(3x^2-6x+10)(x+2) -15$

so  the remainder when $3x^3-2x+5$ divided by x+2  is (-15)

hence the reminder is '-15'
