Answer:

x + 2

Step-by-step explanation:

given

3x³ - 12x ← factor out 3x from each term

= 3x(x² - 4) ← x² - 4 is a difference of squares, hence

= 3x(x - 2)(x + 2) ← fully factorised

hence x + 2 is a factor of the polynomial

If 3 p +3 4 =90
klemol [59]
3p + 34 = 90
3p = 90 - 34
3p = 56
p = 56/3
p = 18.67 (thats rounded)

2r + 44 = 76
2r = 76 - 44
2r = 32
r = 32/2
r = 16

53 + 6s = 1421
6s = 1421 - 53
6s = 1368
s = 1368/6
s = 228

" the product " means multiply
p x r x s = 18.67 x 16 x 228 = 68,108.16
