Question

resueleve loa binomios al cuadrado​

Answer 1

IDENTIDADES NOTABLES

a) (4x - 5y)² = (4x)² + (5y)² - 2 · (4x) · (5y) = 16x²+ 25y² - 40xy

(a - b)² = a² + b² - 2ab

b) (3x + 2y)² = (3x)² + (2y)² + 2 · (3x) · (2y) = 9x² + 4y² + 12xy

(a + b)² = a² + b² + 2ab

c) (2x + 3y)² = (2x)² + (3y)² + 2 · (2x) · (3y) = 4x²  + 9y² + 12xy

(a + b)² = a² + b² + 2ab

d) (-12v + 7z) = (12v)² + (7z)² + 2 · (12v) · (7z) = 144v² + 49z² + 168vz

(a + b)² = a² + b² + 2ab

e) (1/8a - 3/4b)² = (1/8a)² + (3/4b)² - 2 · (1/8a) · (3/4b)

(a - b)² = a² + b² - 2ab
