Question

1. calcula el cuadró de cada binomio
a) (9+4m)²
b) (2x+3)²
c)
$( \frac{2}{3} w - \frac{1}{2}y {)}^{2}$

​

Answer 1

Explicación paso a paso:

Formula de binomio al  cuadrado:

(a ± b)² = a² ± 2ab + b²

Calcula el cuadrado de cada binomio

a)

(6+4m)² = (6)² + 2(6)(4m) + (4m)²

(6+4m)² = 36+48m+16m²

b)

(2x+3)² = (2x)² + 2(2x)(3) + (3)²

(2x+3)² = 4x²+12x+9

c)

(2/3w-1/2y²)² = (2/3w)² - 2(2/3w)(1/2y²) + (1/2y²)²

(2/3w-1/2y²)² = 4/9w²-4/6wy²+1/4y⁴

(2/3w-1/2y²)² = 4/9w²-2/3wy²+1/4y⁴
