What are the basic prime numbers

A prime number is a number that can be divided only by 1 and itself. This means that the number has exactly two factors. For example, 13 is a prime number because 13 can only be divided evenly by 1 and 13. If the number has more than two factors, we say that the number is composite.

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

ok
