Respuesta:
a) (p + q)² = p² + 2pq + q²
(p)(p)= p²
(p)(q)(2)= 2pq
(q)(q)= q²
b) (2m + 3n)² = 4m² + 12mn + 9n²
(2m)(2m)= 4m²
(2m)(3n)(2)= 12mn
(3n)(3n)= 9n²
c) (x² + y³)² = x^4 + 2x²y³ + y^6
(x²)(x²)= x^4
(x²)(y³)(2)= 2x²y³
(y³)(y³)= y^6
d) (10x³ - 9x)² = 100x^6 - 180x^4 + 81x²
(10x³)(10x³)= 100x^6
(10x³)(-9x)(2)= -180x^4
(-9x)(-9x)= +81x²
e) (3m³ - 2n)² = 9m^6 - 12m³n + 4n²
(3m³)(3m³)= 9m^6
(3m³)(-2n)(2)= -12m³n
(-2n)(-2n)= +4n²
f) (0.1x² - 0.1y)² = 0.01x^4 + 0.02x²y + 0.01y²
(0.1x²)(0.1x²)= 0.01x^4
(0.1x²)(-0.1y)(2)= 0.02x²y
(-0.1y)(-0.1y)= +0.01y²
g) (0.3a + 0.5b)² = 0.09a² + 0.3ab + 0.25b²
(0.3a)(0.3a)= 0.09a²
(0.3a)(0.5b)(2)= 0.3ab
(0.5b)(0.5b)= 0.25b²
h) (p² + q³)² = p^4 + 2p²q³ + q^6
(p²)(p²)= p^4
(p²)(q³)(2)= 2p²q³
(q³)(q³)= q^6
i) (5a + 8b)² = 25a² + 80ab + 64b²
(5a)(5a)= 25a²
(5a)(8b)(2)= 80ab
(8b)(8b)= 64b²
j) (m³ + n^4)² = m^6 + 2m³n^4 + n^8
(m³)(m³)= m^6
(m³)(n^4)(2)= 2m³n^4
(n^4)(n^4)= n^8
k) (5a² - 9b)² = 25a^4 - 90a²b + 81b²
(5a²)(5a²)= 25a^4
(5a²)(-9b)(2)= -90a²b
(-9b)(-9b)= +81b²
l) (1/4a + b²)² = 1/16a² + 1/2ab² + b^4
(1/4a)(1/4a)= 1/16a²
(1/4a)(b²)(2)= 1/2ab²
(b²)(b²)= b^4
1) (2x + 2y)(2x - 2y) = 4x² - 4y²
(2x)(2x)= 4x²
(2y)(-2y)= -4y²
2) (a + 4b)(a - 4b) = a² - 16b²
(a)(a)= a²
(4b)(-4b)= -16b²
3) (3a + 2b)(3a - 2b) = 9a² - 4b²
(3a)(3a)= 9a²
(2b)(-2b)= -4b²
4) (2x² - 5y)(2x² + 5y) = 4x^4 - 25y²
(2x²)(2x²)= 4x^4
(-5y)(5y)= -25y²
7) (1 - 3ax)(3ax + 1) = 1 - 9a²x²
(1)(1)= 1
(-3ax)(3ax)= -9a²x²
8) (2m + 9)(2m - 9) = 4m² - 81
(2m)(2m)= 4m²
(9)(-9)= -81
9) (a³ - b²)(a³ + b²) = a^6 - b^4
(a³)(a³)= a^6
(-b²)(b²)= -b^4
10) (y² - 3y)(y² + 3y) = y^4 - 9y²
(y²)(y²)= y^4
(-3y)(3y)= -9y²
