Answer 1

$\bold{Question}$

what must be subtracted from x³ - 3x² + 5x - 1 to get 2x³ + x² - 4x + 2 ?

$\bold{Solution}$

$\bold{x³ - 3x² + 5x - 1\: P(x)=2x³ + x² - 4x + 2}$

$\bold{P(x)=(x³ - 3x² + 5x - 1)-(2x³ + x² - 4x + 2)}$

$\bold{P(x)=x³ −2x³−3x² −x²+5x+4x−1−2}$

$\bold{∴p(x)=−x³−4x² +9x−3}$

Answer:

[tex]what must be subtracted from x³ - 3x² + 5x - 1 to get 2x³ + x² - 4x + 2 ?

��������Solution

�3−3�2+5�−1�(�)=2�3+�2−4�+2x3−3x2+5x−1P(x)=2x3+x2−4x+2

�(�)=(�3−3�2+5�−1)−(2�3+�2−4�+2)P(x)=(x3−3x2+5x−1)−(2x3+x2−4x+2)

�(�)=�3−2�3−3�2−�2+5�+4�−1−2P(x)=x3−2x3−3x2−x2+5x+4x−1−2

∴�(�)=−�3−4�2+9�−3∴p(x)=−x3−4x2+9x−3
