Question

Resolver los siguientes ejercicios por fa es urgente gracias
(m+n)^2
(2a^2-5b)^3
(3y-x^2)^3
(10-z)^3
(2x+4)^3

Answer 1

(m+n)²= m² + 2mn + n²

(2a²-5b)³
=(2a²)³- 3(2a²)²(5b) + 3(2a²)(5b)² - (5b)³
=8a⁶ - 60a⁴ + 150a²b²- 125b³

(3y - x²)³
=(3y)³ - 3(3y)²(x²) + 3(3y)(x²)² - (x²)³
=27y³ -27y²x² + 9yx⁴ - x⁶

(10-z)³
=(10)³ - 3(10)²(z) + 3(10)(z)² - (z)³
=1000 - 300z + 30z² - z³

(2x + 4)³
=(2x)³ + 3(2x)²(4) + 3(2x)(4)² + (4)³
=8x³ + 46x² + 96x + 64

Espero que te sirva! Saludos!
