The correct answer is -2.6, so *B* is the correct answer

Answer from: naiomireyes74p2aybs

A is INCORRECT because Lucita's estimate is about right and if the decimal point was to the left of 2, then the answer would be -0.26 which is still too small.

B is CORRECT because again Lucita's estimate is about right and if the decimal is to the left of six the number would be -2.6 which is close to her estimate (-3)

C is INCORRECT because it is saying that -0.026 is the correct answer and Lucita's estimate was just too small which is incorrect since we know -0.026 is actually what is too small.

D is INCORRECT because it is saying that -0.026 is correct and if her estimate (-3) was too high, it would be bigger than the number she got which was -0.026 and regardless of anything we know -3 is not bigger that -0.026.

Answer from: Quest

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2 polynomial long division

dividing : x4+5x3-4x2-8x+6

("dividend")

by : x-1 ("divisor")

dividend x4 + 5x3 - 4x2 - 8x + 6

- divisor * x3 x4 - x3

remainder 6x3 - 4x2 - 8x + 6

- divisor * 6x2 6x3 - 6x2

remainder 2x2 - 8x + 6

- divisor * 2x1 2x2 - 2x

remainder - 6x + 6

- divisor * -6x0 - 6x + 6

remainder 0

quotient : x3+6x2+2x-6 remainder: 0
