Here is your answer :-

☑️☑️Answer:

15 is the remainder when 4x³ - 3x² + 2x - 1 is divided by x + 2.

Step-by-step explanation:

Given, Dividend = 4x³ - 3x² + 2x - 1

and Divisor = x + 2

Let p(x) = 4x³ - 3x² + 2x - 1

We use Remainder Theorem to find remainder.

Remainder Theorem states that let p(x) be any polynomial of degree greater than or equal to one and let a be any real number. If p(x) is divided by the linear polynomial x - a, then the remainder is p(a).

We have ,

p(-2) = 4(-2)³ - 3(-2)² + 2(-2) - 1 = 4 × 8 - 3 × 4 - 4 - 1 = 32 - 12 -5 = 15

Therefore, 15 is the remainder when 4x³ - 3x² + 2x - 1 is divided by x + 2.✔️✔️✔️✔️
