Question

(5x+1/2y)*=

(4x-2z)*=

(1/2x-y*)*=

(1/2a+1/3b)*=

(a-3b)(a+3b)=

(1/2m+n*)(1/2m-n*)=

(p/3-3q)(3q+p/3)=

(x2y+2xy*)(x*y-2xy)=

Answer 1

Cześć;)

( (5x+1/2y)*=5x+1/2y)(5x+1/2y)=25x*+6xy+6xy+0,25y*

(4x-2z)*=(4x-2z)(4x-2z)=16x*-8xz-8xz+4z*

(1/2x-y*)*=(1/2x-y*)(1/2x-y*)=0,25x*-1/2xy*-1/2xy+y do 4

(1/2a+1/3b)(1/2a+1/3b)=0,25a*+0,16ab+16ab+0,11b*

(a-3b)(a+3b)=a*+3ab-3ab-9b*

(1/2m+n*)(1/2m-n*)=0,25m*-1/2mn*+1/2mn*-n do 4

(p/3-3q)(3q+p/3)=pq+p*/9-9q*-pq

(x2y+2xy*)(x*y-2xy)=2x do3y-4x*y*+2x do3y do3-4x*y do3

 

Mam nadzieję że pomogłam, prosiłabym o naj ;)
