Question

x cube minus 4 x square minus x + 1 is equal to x minus 2 the whole cube​

Answer 1

Answer:

Step-by-step explanation:

x³ - 4x² - x + 1 = (x-2)³

x³ - 4x² - x + 1 = x³ - 6x² + 12x - 8

=> 2x² - 13x + 9 = 0

2x² - 13x + 9 = 0 is a quadratic equation

// to find values of x,  use  x = [- b ± √(b² - 4ac)]  / 2a

x = 13 ± √[(13)² - 4(2)(9)] / 2 * 2

  = 13 ±√97 /4

x = [13 + √97] / 4 or x = [13 - √97] / 4

Answer 2

Answer:

the quadratic equation formed is 2x^2 - 13x + 9 = 0
