Sagot: Ang form ng Vertex ay # y = (x + 7/2) ^ 2-57 / 4 # at vertex ay #(-3 1/2,-14 1/4)# Paliwanag: # y = x ^ 2 + 7x-2 # = # x ^ 2 + 2 × 7/2 × x + (7/2) ^ 2- (7/2) ^ 2-2 # = # (x + 7/2) ^ 2-49 / 4-2 # = # (x + 7/2) ^ 2-57 / 4 # Samakatuwid, ang vertex form ay # y = (x + 7/2) ^ 2-57 / 4 # at vertex ay #(-7/2,-57/4)# o #(-3 1/2,-14 1/4)#
