me podrian ayudar con esto porfa

Answer 1

(3r² - r)(- 2r)
(3r²)(- 2r) - (r)(- 2r)
- 6r³ + 2r²

(a³ - 2a² - 6a)(2ab)
(a³)(2b) - (2a²)(2b) - (6a)(2ab)
2a³b - 4a²b - 12a²b
2a³b - 16a²b

(m⁴ - 2m²n² - 5n⁴)(?)

(aⁿ - aⁿ⁻¹ - aⁿ⁻³)(?)

(a - b)(a - b)
a² - ab - ab + b²
a² - 2ab + b²

(a - 3)(a - 2)
a² - 2a - 3a + 6
a² - 5a + 6

(x - 7)(x - 5)
x² - 5x - 7x + 35
x² - 12x + 35
