Ejercicio 1Resuelve los siguientes productos notables1. (a+6)2 R/: 2. (5m+3)2 R/: 3. (2x+1)2 R/: 4. (m7-1)2 R/: 5. (6x5-4)2 R/: 6. (a – b)2 R/:.

Answer 1

Explicación paso a paso:

Formula de binomio al  cuadrado:

(a ± b)² = a² ± 2ab + b²

Resuelve los siguientes productos notables:

1.

(a+6)² = (a)² + 2(a)(6) + (6)²

(a+6)² = a²+12a+36

2.

(5m+3)² = (5m)² + 2(5m)(3) + (3)²

(5m+3)² = 25m²+30m+9

3.

(2x+1)² = (2x)² + 2(2x)(1) + (1)²

(2x+1)² = 4x²+4x+1

4.

(m⁷-1)² = (m⁷)² - 2(m⁷)(1) + (1)²

(m⁷-1)² = m¹⁴-2m⁷+1

5.

(5x⁵-4)² = (5x⁵)² - 2(5x⁵)(4) + (4)²

(5x⁵-4)² = 25x¹⁰-40x⁵+16

6.

(a-b)² = (a)² - 2(a)(b) + (b)²

(a-b)² = a²-2ab+b²
