Graph the solutions of the inequality on a number line.
c< 5

Step-by-step explanation:

The given inequality is C < 5

To draw this inequality on a number line we should always remember few things.

1). If the expression is in the form of less than to any given number we draw an arrow starting from the given number with a hole.

2) For an equality hole is replaced by a solid point.

Now we take the expression given

We will draw an arrow towards -10, with a hole as done in the figure attached.

- 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
