Question

Porfaaaaaaa Necesito ayuda con estos binomios al cubo
(5 - 2n)³
(6 - 4y)³
(2x+3y)³
(2x²+5y⁴)³​

Answer 1

Explicación paso a paso:

(5–2n)³ = (5)³ – 3(5)²(2n) + 3(5)(2n)² – (2n)³

= 125 – 150n + 60n² – 8n³

(6–4y)³ = (6)³ – 3(6)²(4y) + 3(6)(4y)² – (4y)³

= 216 – 432y + 288y² – 64y³

(2x + 3y)³ = (2x)³ + 3(2x)²(3y) + 3(2x)(3y)² + (3y)³

= 8x³ + 36x²y + 54xy² + 27y³

(2x² + 5y⁴)³ = (2x²)³ + 3(2x²)²(5y⁴) + 3(2x²)(5y⁴)² + (5y⁴)³

= 8x^6 + 60x⁴y⁴ + 150x²y^8 + 125y^12
