Question

alguien sabe porfavor espara hoy se lo pido​

Answer 1

RESPUESTA: 1.(x+4)²= x²+ 2×x×4+4²= x²+ 8x +16

2.(2x-5)²= 2x²-2×2x×5+5²= 4x²-20x+25

3.(1-6x)²=1²-2·1·6x+6x²=1-12x+36x²

4.(5x-3)²=5x²-2·5x·3+3²=25x²-30x+9

5.(3+4a)²=3²+2·3·4a+4a²=9+24a+16a²

6.(2b+7)²=2b²+2·2b·7+7²= 4b²+28b+49

7.(3-y)²=3²-2·3·y+y²= 9-6y+y²

8.(4z+1)²= 4z²+2·4z·1+1²=16z²+16z+1

esperame un ratito y te mando las demas

9.(3xy-1)²=3xy²-2·3xy·1+1²=9xy²-6xy+1

10.(x+$\frac{1}{2}$)= x²+2·x·$\\ \frac{1}{2}$+$\frac{1}{2}$²=x²+2$\frac{1}{2}$x+2

11.2x²-5²=4x²-25

12.x²+1²=x²+1

13.(x-y)²=x²-2·x·y+y²=x²-2xy+y²

14.3x²-1²=9x²-1

15.x²-1²=x²-1

16.(y+6)²=y²+2·y·6+6²=y²+12y+36

17.(3z-2)²=3z²-2·3z·2+2²=9z²-12z+4²

18.(7-x)²=7²-2·7·x+x²= 49-14x+x²

19.(x-2y)²=x²-2·x·2y+2y²=x²-4xy+4y²

20.(4+7b)²=4²+2·4·7b+7b²= 16²+56b+49b²
