A student showed the steps below while solving the inequality X-41 S1 by graphing.
Step 1:
Step 2:
Write a system of equations: Y1 = [X-411
Graph the two equations:
+
-3
-2 -1
1
2
3
4
5
6
7
Step 3:
Identify the values of x for which Y1 592:
x = 3 or x = 5

it would to have a graph or something ! but i had this question so its false

step-by-step explanation:

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

i would say b) is your answer

sorry if im wrong
