Sagot:
Ang form ng Vertex ng equation ay # y = (x + 22.5) ^ 2 - 475.25 #
Paliwanag:
#y = x ^ 2 + 45x + 31 o y = x ^ 2 + 45x + (45/2) ^ 2 - (45/2) ^ 2 + 31 #
# y = (x + 45/2) ^ 2 -2025/4 +31 o y = (x + 45/2) ^ 2 - 1901/4 # o
# y = (x + 22.5) ^ 2 - 475.25 #. Paghahambing sa vertex form ng
equation # y = a (x-h) ^ 2 + k; (h, k) # pagiging kaitaasan, nakikita natin dito
# h = -22.5, k = -475.25:. # Nasa Vertex # (-22.5,-475.25)#
at vertex form ng equation ay # y = (x + 22.5) ^ 2 - 475.25 # Ans
