Answer 1

Respuesta:

$(a+b)^{3} =a^{3} +3a^{2}b+3ab^{2}+b^{3}$

1)

$(x+5)^{3} = (x)^{3} +3(x)^{2} (5) + 3(x)(5)^{2} +(5)^{3} = x^{3} + 15x^{2} +75x+125$

2)

$(2x+6)^{3} = (2x)^{3} + 3(2x)^{2} (6) + 3(2x)(6)^{2} + (6)^{3} = 8x^{3} +72x^{2} +216x+216$

3)

$(2x+4y)^{3} = (2x)^{3}+3(2x)^{2}(4y)+3(2x)(4y)^{2}+(4y)^{3} = 8x^{3}+48x^{2} y+96xy^{2}+64y^{3}$

4)

$(2x+3)^{3} = (2x)^{3} +3(2x)^{2} (3)+3(2x)(3)^{2}+(3)^{3} =8x^{3}+36x^{2}+54x+27$

5)

$(3x+6y)^{3}=(3x)^{3}+3(3x)^{2}(6y)+3(3x)(6y)^{2}+(6y)^{3}=27x^{3} +162x^{2}y+324xy^{2}+216y^{3}$

6)

$(4x+2y)^{3} = (4x)^{3} + 3(4x)^{2} (2y)+3(4x)(2y)^{2}+(2y)^{3}=64x^{3}+96x^{2}y+48xy^{2}+8y^{3}$
