Please.. Bantu aku... Poin nya lumayan lhoooh..
a) x² - 9x = 0
b) 4x² - 3x -10 = 0
c) x² - 36 = 0
d) 12x² - 23x + 5 = 0
Please.. Bantu aku... Poin nya lumayan lhoooh..
9x = 9×9 = 81
a = 81-81=0
b) 4x² = 4×2×2 = 16
3x = 3×2 = 6
b = 16-6-10 = 0
c) x² = 6×6 =36
c = 36-36 = 0
Maaf cuma bisa jawab sampe c yg d susah banget... Maaf ya,,,
