Question

Calcula los siguientes productos notables

A) (6x + 1)²
b) (9m⁴ - 3n)²
c) (11m⁴n² - 7m⁵n³)²

Answer 1

Explicación paso a paso:

a) (6x + 1)² = (6x)² + 2(6x)(1) + 1² = 36x² +  12x + 1

b) (9m⁴ - 3n)² = (9m⁴)² - 2(9m⁴)(3n) + (3n)² = $81m^{8}$ - 36 m⁴n + 9n²

c) (11m⁴n² - 7m⁵n³)² = (11m⁴n²)² - 2(11m⁴n²)(7m⁵n³) + (7m⁵n³)²

= 121$m^{8}$n⁴ - 154$m^{9} n^{5}$ + 49$m^{10} n^{6}$
