Factor the polynomial F(x) =x^3-x^2-4x+4 completely.

Norma-Jean [14]

Answer:

Step-by-step explanation:

PART 1:

Possible roots by noticing the coefficient of first term:

x = 1, -1

PART 2:

1 | 1 -1 -4 4

1 0 -4 0

The remainder is zero, hence one factor is (x-1)

PART 3:

$x^3-x^2-4x+4=(x^2-4)(x-1)\\\\x^3-x^2-4x+4=(x+2)(x-2)(x-1)$

PART 4:

$f(x)=(x+2)(x-2)(x-1)\\\\=(x^2-4)(x-1)\\\\=x^3-4x-x^2+4\\\\=x^3-x^2-4x+4$

Area and volume math question pretty simple please help no explanation needed just answers

Svetlanka [38]

Solution ,

length = 4m

breadth = 1.2m

height = 0.3m

Now

Area = l × b

= 4m × 1.2 m

= 4.8m²

Now

Volume = l × b × h

= 4m × 1.2m × 0.3m

= 1.44 m³
