Write the polynomial given the roots: 2,-1, and -2

x^3 + x^2 - 4x - 4.

Step-by-step explanation:

In factor form we have:

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

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

The last 2 factors simplify to the difference of 2 squares

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

= x^3 - 4x + x^2 - 4

= x^3 + x^2 - 4x - 4.

the answer is 3/5

step-by-step explanation:

first divide 24 divided by 8 because that is the least common multiple

then divide 40 by 8

then you will get 3/5.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
