X is a positive integer. 33 + x is a positive integer.
Work out the four possible values of X,

Step-by-step explanation:

An integer is a number without decimal part i.e a whole number. Since x is a positive integer, it could be replaced by any positive integer. So that 33 + x would also be a positive integer.

Four possible values of x are:

i. Let x = 10, then;

33 + x = 33 + 10

          = 43

ii. Let x = 2, then;

33 + x = 33 + 2

          = 35

iii. Let x = 25, then;

33 + x = 33 + 25

          = 58

iv. Let x = 30, then;

33 + x = 33 + 30

          = 63

- 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
