Question

find the remainder when 4x³-3x²4x³-3x²-5x+7 is divided by (x-3)​

Answer 1

Answer:

x= -2

$4 {x}^{3} - 3 {x}^{2} + 2 {x}^{} - 4$

4 (-8)-3 (4)+2(-2)-4

-32-12-4-4

-52

remainder is-52

Answer 2

Answer:

Step-by-step explanation:

Let p(x) = 4x³-3x²4x³-3x²-5x+7

= - 12x⁵ + 4x³ - 3x² - 5x + 7

g(x) = (x-3)

Using remainder theorem, remainder is given by

P(3) = -12× 3⁵ + 4 × 3³ - 3×3² - 5×3 + 7

= -12 × 243 + 4×27 - 27 - 15 + 7

= -2916 + 108 - 42 + 7

= - 2958 + 115

= -2843 Ans
