Magda: alo tu chodzi o narysowanie tego samemu a nie za pomoca programu.

aniabb: wybierasz sobie x ..obliczasz y i rysujesz kropki

aniabb: a) x²+2x+1−3(y²+2y+1)−6=0 (x+1)² −3(y+1)² =6 //6 (x+1)²/6 − (y+1)²/2 = 1 hiperbola

aniabb: b) (x+y)² +10(x+y)+16=0 (x+y)² +2(x+y)+8(x+y)+16=0 (x+y)(x+y+2)+8(x+y+2)=0 (x+y+8)(x+y+2)=0 iloczyn=0 jak czynniki=0 2 proste x+y+8=0 x+y+2=0
