Write the absolute value equation that has two solutions x=5 and x=11

|8-x|=3

Step-by-step explanation:

Find the average

11+5=16

16*1/2=8

8-5=3

8-11=-3

|3|=|-3|

|8-x|=3

- 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
