Question

pueden ayudarme!!!!!!!​

Answer 1

Respuesta:

Espero haberte ayudado :))

Explicación paso a paso:

a) (x+1)² = x²+2(x)(1)+1² = x²+2x+1

b) (x+8)² = x²+2(x)(8)+8² = x²+16x+64

c) (3x+5)² = (3x)²+2(3x)(5)+5² = 9x²+30x+25

d) (6x-2)² = (6x)²-2(6x)(2)+2² = 36x²-24x+4

e) (9x-y)² = (9x)²-2(9x)(y)+y² = 81x²-18xy+y²

f) (x+9)(x-9) = x²-9² = x²-81

g) (x+3)(x-3) = x²-3² = x²-9

h) (7x+y)(7x-y) = (7x)²-y² = 49x²-y²

i) (x+2)³ = x³+3(x)²(2)+3(x)(2)²+2³ = x³+6x²+12x+8

j) (x-8)³ = x³-3(x)²(8)+3(x)(8)²-8³ = x³-24x²+192x-512

k) (3x+1)³ = (3x)³+3(3x)²(1)+3(3x)(1)²+1³ = 27x³+27x²+9x+1

l) (4x-2y)³ = (4x)³-3(4x)²(2y)+3(4x)(2y)²-(2y)³ = 64x³-96x²y+48xy²-8y³
