Z podanych wzorów wyznacz
a) P=2*(a*b+b*c+a*c) wyznacz ab) P= (a+b+c)/2 * (a+b-c)/2 wyznacz a,c (a,b,c >0)
a)P=2(ab+bc+ac)
P=2ab+2bc+2ac/-(2bc+2ac)
P-(2ab+2ac)=2ab/:2
p-(2ab+2ac)/2=ab
b)P=(a+b+c)/2 * (a+b-c)/2
P=(2a+2b)/2/-b
P-b=a
c niestety nie wiem jak ;p
P=2ab+2bc+2ac
p-(2ab+2ac)/2=ab/:b
p-(2ab+2ac)/2/b=a
a=p-(2ab+2ac)/2*1/b
a=p-(2ab+2ac)/2b
