Question

Resuelve:
(x+8)²
(y+5)²
(4-m)²
(3+x)²
​

Answer 1

Respuesta:

Formula de binomio al  cuadrado:

(a ± b)² = a² ± 2ab + b²

Formula de binomios conjugados:

(a + b)(a - b) = a² - b²

Explicación paso a paso:

1:

(x+8)² = (x)² + 2(x)(8) + (8)²

(x+8)² = x²+16x+64

2:

(x-7)² = (x)² - 2(x)(7) + (7)²

(x-7)² = x²-14x+49

3:

(3x+5)² = (3x)² + 2(3x)(5) + (5)²

(3x+5)² = 9x²+30x+25

4:

(3-x)² = (3)² - 2(3)(x) + (x)²

(3-x)² = 9-6x+x²  

5:

(x-7)(x+7)

(x)² - (7)²

x²-49

6:

(8-x)(x+8)

(8)(x) + (8)(8) + (-x)(x) + (-x)(8)

8x+64-x²-8x
