Sagot:
# y = (x - (- 9/2)) ^ 2 + (- 169/4) #
Paliwanag:
Pangkalahatang tuktok na form:
#color (white) ("XXX") y = (x-a) ^ 2 + b # na may kaitaasan sa # (a, b) #
#rarrcolor (white) ("XXX") y = x ^ 2 + 9x-22 #
#rarrcolor (white) ("XXX") y = x ^ 2 + 9xcolor (red) (+ (9/2) ^ 2) -22color (red) (- (9/2) ^ 2)
#rarrcolor (puti) ("XXX") y = (x + 9/2) ^ 2-22-81 / 4 #
#rarrcolor (puti) ("XXX") y = (x - (- 9/2)) ^ 2 + (- 169/4) #
na kung saan ay ang vertex form na may vertex sa #(-9/2,-169/4)#
