# 3y = -5x ^ 2-x + 7 #
Hatiin ang magkabilang panig ng
#y = 1/3 (-5x ^ 2-x + 7) #
#color (white) (y) = -5/3 (x ^ 2 + 1 / 5x-7/5) #
#color (white) (y) = -5/3 (x ^ 2 + 2 (1/10) x + 1 / 100-141 / 100) #
#color (white) (y) = -5/3 ((x + 1/10) ^ 2-141 / 100) #
#color (white) (y) = -5/3 (x + 1/10) ^ 2 + 141/60 #
#color (white) (y) = -5/3 (x - (- 1/10)) ^ 2 + 141/60 #
Ang equation:
#y = -5/3 (x - (- 1/10)) ^ 2 + 141/60 #
ay nasa anyo:
#y = a (x-h) ^ 2 + k #
na kung saan ay vertex form para sa isang parabola na may kaitaasan
