The zeros for f(x) = x4 – 3x3 – 4x2 + 12x are
A. (0,2,3)
B. (0, +2,3)
C. (0,2-3)
D. (0, 2, +3)

A

Step-by-step explanation: I got 0,-2,2,3

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

sorry i need the points
