pomozcie mi zrobic zadanie z matmy. Prosilbym szybko. Dzieki z góry. 1.(x +5z)(b-11) 2.(a-6b)(-8 -13b) 3.(a - 4b)(2b - 7a) 4.(x+2+y)(z+1) 5.(a+b)(7-b+4c) 6.(p-2s+5t)(5p-3) Obliczcie mi to!. Dzieki Pozdrawiam Popek :)

1.(x +5z)(b-11)=xb-11x+5zb-55z 2.(a-6b)(-8 -13b)=-8a+13ab+48b+78b² 3.(a - 4b)(2b - 7a)=2ab-7a²-8b²+28ab=-7a²-8b²+3ab 4.(x+2+y)(z+1)=xz+z+2z+3+yz+y 5.(a+b)(7-b+4c)=7a+ab+4ac+7b+b²+4c 6.(p-2s+5t)(5p-3)=5p²-3p310ps+6s+25pt-15t pozdrawiam Nala.;p

1. (x +5z)(b-11) = bx-11x+5bz-55z 2. (a-6b)(-8 -13b) = -8a-13ab+48b+78b2 3. (a - 4b)(2b - 7a) = 2ab-7a2-8b2+28ab = 30ab-7a2-8b2 4. (x+2+y)(z+1) = xz+x+2z+2+yz+y 5. (a+b)(7-b+4c) = 7a-ab+4ac+7b-b2+4bc 6. (p-2s+5t)(5p-3) = 5p2-3p-10ps+6s+25pt-15t
