2x² - 4x=0 x=5 x = -5 2x (x-2)=0 Jadi, tip={ -sis? 2x=0 X-2=0 x=0 atau x= 2 5 x2 +10% +21 = 0 Jadi, Himpunan penyelesaian (x+7) (x+3) addlah O, 2 } x=-7 X=-3 Jadi, HP ={ -7,-3 } x² + 8x=0 X (x+8)=0 ③ x² - 2x-15=0 x=0 X+8=0 ( 8-5) (x+3) x = -8 x=5 x = -3 Jads i Hp = { 01-83 Jadi, HP = { -3,5} 4X² - 36 = 0 ③ x² +10x+25=0 4X2 = 36 (x+5) (x+5) x² -9 x=-5 X Х =r9 Jadi, HP = {s} x=3 x=-3 Jadi, tp = { -3,3% ® 82 +68+9 = 0 (X+3)(x+3) 25 - x² = 0 X=-3 25 = x² Judi , HP ={-3% X = V25 People become tools when they stop esiding quoedons BUO = . ca
