What must be subtracted from x^4 + 2x^2 - 3x + 7 to get x^3 + x^2 + x

1.	What must be subtracted from x^4 + 2x^2 - 3x + 7 to get x^3 + x^2 + x - 1
Answer» ONG>ANSWER: x⁴ - x³ + x² - 4x + 8 Step-by-step explanation: (x⁴ + 2x² - 3x + 7) - A = (x³ + x² + X - 1) A = (x⁴ + 2x² - 3x + 7) - (x³ + x² + x - 1) A = x⁴ + 2x² - 3x + 7 - x³ - x² - x + 1 A = x⁴ - x³ + x² - 4x + 8

What must be subtracted from x^4 + 2x^2 - 3x + 7 to get x^3 + x^2 + x - 1

Answer» ONG>ANSWER:

x⁴ - x³ + x² - 4x + 8

Step-by-step explanation:

(x⁴ + 2x² - 3x + 7) - A = (x³ + x² + X - 1)

A = (x⁴ + 2x² - 3x + 7) - (x³ + x² + x - 1)

A = x⁴ + 2x² - 3x + 7 - x³ - x² - x + 1

A = x⁴ - x³ + x² - 4x + 8
