Cevap:
• y = 1/5 (x-10/7) ^ 2 + 47/245 #
Açıklama:
1. / 5x ^ 2-4 / 7x + 3/5 #
# = 1/5 (x ^ 2-20 / 7x) + 3/5 #
# = 1/5 (x ^ 2-20 / 7x + (20 / 7divide2) ^ 2- (20 / 7divide2) ^ 2) + 3/5 #
# = 1/5 (x-10/7) ^ 2-1 / 5 * 100/49 + 3/5 #
# = 1/5 (x-10/7) ^ 2 + (* 49-100 3) / (* 49 5) #
# = 1/5 (x-10/7) ^ 2 + 47/245 #
