Question

Resuelve los siguientes productos notables, de acuerdo con los ejemplos anteriores
1. (3m+1 2n)2=
2. (2x-5y)=
3. (8x-7y)2=
4. (9c-11d)-
5. (20+5b)2=
6. (3y+8z)?​

Answer 1

Respuesta:

1-(3m+12n)2= 6m + 24m

2-(2x-5y)= 4x -10y

3-(8x-7y)2= 16x -14y

4.(9c-11d)= 18c -22d

5.(20+5b)2= 40 + 10b

6.(3y+8z)= 6y + 16 z

Answer 2

Respuesta:

Espero q les ayude

Explicación paso a paso:

1.(3m+12n)²=(3m+2n)(3m+2n)=(3m)²+3m(12n(12n)²=9m²+72mn+144

2. (2x-5y)²=(2x-5y)(2x-5y)=(2x)²-2x(5y)-2x(5y)+5²=4x-20xy+25

3.(8x-7y)²=(8x-7y)(8x-7y)=(8x)²-8x(7y)-8x(7y)+7²=64x-112xy-49

4. (9c-11d)²=(9c-11d)(9c-11d)=(9c)²-9c(11d)-9c(11d)+11²=81c-198cd+22

5. (2a+5b)²=(2a+5b)(2a+5b)=(2a)²+2a(5b)+2a(5b)+5b²=4a+20ab+25

6.(3y+8z)²=(3y+8z)(3y+8z)=(3y)²+3y(8z)+3y(8z)+8z²=9y²+48y²+64
