Question

what should be subtracted from x cube + 2 x square - 3 x + 10, so that the difference is a multiple of (x - 2)

please give step by step explanation don't give spam ans​

Answer 1

Step-by-step explanation:

[x³ + 2x² - 3 + 10] - y = 3(x - 2)

[I assume 3 times (x -2) for my convenience.]

• x³ + 2x² + 7 - y = 3x + 6
• x³ + 2x² - 3x - y = 6 - 7
• x³ + 2x² - 3x - y = -1
• -y = (-1) - x³ - 2x² + 3x

Therefore, y = 1 + x³ + 2x² - 3x

Hope it helps you, friend !
