Me ashudan por favor es urgente
1-(2xy-2x)(x+3)
2-(2x-y+7)(x3y-xy2)
3-(x2+y2-1)(x-2y)
4-(2u-3v+2)(u+v+1)
5-(2ab-a2+5b2)(a-b+c)
6-(m3-3m2+3m)(2m+1)
7-(x2+y2+2+y)(x+y)
1-(2xy-2x)(x+3)
2-(2x-y+7)(x3y-xy2)
3-(x2+y2-1)(x-2y)
4-(2u-3v+2)(u+v+1)
5-(2ab-a2+5b2)(a-b+c)
6-(m3-3m2+3m)(2m+1)
7-(x2+y2+2+y)(x+y)
1. (2xy - 2x)(x+3) = 2x²y + 6xy - 2x² - 6x
2. (2x - y +7)( x³y - xy²) = 2x⁴y - 2x²y² - x³y² - xy³ + 7x³y - 7xy²
3. (x²+y²-1)(x-2y) = x³-2x²y + xy² - 2y³ -x + 2y
4. (2u-3v+2)(u+v+1) = 2u²+2uv+2u-3uv-3v²-3v+2u+2v+2=2u²-uv+4u-v-3v²+2-3v
5. (2ab-a²+5b²)(a-b+c)= 2a²b-2ab²+2abc-a³+a²b-a²c+5b²a-5b³+5b²c= 3a²b+3ab²+2abc+5b²c-a³-a²c-5b³
6. (m³-3m²+3m)(2m+1) = 2m⁴+m³-6m³-3m²+6m²+3m=2m⁴-5m³+3m²+3m
7. (x²+y²+2+y)(x+y)= x³+x²y+xy²+y³+2x+2y+xy+y²
espero haberte ayudado... suerte que tengas un lindo dia <3
