Determine if x + 2 is a factor of p(x) = x ^4 + 3x^ 3 + 4x ^2 - 8 and explain why.

zlopas [31]

X^4+ 3x^3+4x^2-8 | x+2 = x^3+x^2+2x-4
-x^4-2x^3
-----------------------
x^3+4x^2-8
-x^3-2x^2
-------------------------
2x^2-8
-2x^2-4x
--------------
-4x-8
4x+8
----------------------------
/ /

is a factor because (x+2)(x^3+x^2+2x-4)=x^4+3x^3+4x^2-8

The correct answer would be A

Take the left triangle, flip it and put it on the right side. This should resemble a rectangle. Then calculate

9cm + 7cm = 16cm
6cm x 16cm = 93cm squared

The correct answer is A, hoped this helped!
