Answer:

B. (x+4)(x+i)(x-i)

Step-by-step explanation:

Let P(x)=x^3-4x^2+x-4

We can factor this polynomial by grouping:

P(x)=x^2(x-4)+1(x-4)

We factor further to obtain:

P(x)=(x^2+1)(x-4)

P(x)=(x^2-\sqrt{-1}^2)(x-4)

We apply difference of two squares to get:

P(x)=(x-i)(x+i)(x-4)

Draw a triangle that is both a right triangle and an isosceles triangle. You can use either pencil and paper, or a draw program.
dem82 [27]
2. measurements can be any to complementary angles.
   for example, 60 & 30
3. the 2 sides are equal. Since it is an isosceles triangle.
4.an equi.triangle can never be right angled. Since, all angles are 60° in an             equi.triangle.
5. right triangle can never have an obtuse angle since one angle is already          90°. therefore the other two agles are supposed to be acute angles.[ since        sum of all angles in a triangle is 180°]
