Question

Me ayudan es de Binomio al cuadrado

Answer 1

Respuesta:

1. (x + 1)^2 = (x + 1)(x + 1) = x^2 + x + x + 1 = x^2 + 2x +1

2. (7x+5y) = (7x+5y)( 7x+5y) = 49x^2 + 35xy + 35xy + 25y^2 = 49x^2 + 70 xy + 25y^2

3. (2ab + 3c)^2 = (2ab + 3c)(2ab + 3c) = 4a^2b^2 + 6abc + 6abc + 9c^2 = 4a^2b^2 + 12abc + 9c^2

4. (4mn - 8)^2 = (4mn - 8)(4mn - 8) = 16m^2n^2 - 32mn - 32mn + 64 = 16m^2n^2 - 64mn + 64

5. (x^2y - 3z)^2 = (x^2y - 3z)(x^2y - 3z) = x^4y^2 - 3x^2yz - 3x^2yz + 9z^4 = x^4y^2 - 6x^2yz + 9z^4

6. (-2x^3 - 3y^2)^2 = (-2x^3 - 3y^2)(-2x^3 - 3y^2) = 4x^6 + 6x^3y^2 + 6x^3y^2 + 9y^4 = 4x^6 + 12x^3y^2 + 9y^4

7. (5x - 1)^2 = (5x - 1)(5x - 1) = 25x^2 - 5x - 5x + 1 = 25x^2 - 10x + 1

8. (1 - x)^2 = (1 - x)(1 - x) = 1 - x - x + x^2 = 1 - 2x + x^2
