Question

X cube minus 2 X square + 5 x Dived3x

Answer 1

Answer:

Let x-1 be a factor of x3-2x2-5x+6

putting x= 1

x(1) = (1)³ - 2(1)² - 5(1) + 6

x(1) = 1 - 2 -5 +6

x(1)= 7 - 7

x(1) = 0

Now x3-2x2-5x+6 divided by (x - 1)

It gives you x² - x - 6

Now, x² - x - 6 (x-1)

= x² + 2x - 3x - 6 (x-1)

= x ( x+2) -3 (x+2) (x-1)

= (x-3) (x+2) (x-1)
