Cevap:
#A (x) = (x-3) * (x-3) #
Açıklama:
Sahibiz, #A (x) = x ^ 2-6x + 4 #
Yani, #color (beyaz) (xxx) A (x) + 5 = (x ^ 2-6x + 4) + 5 #
#rArr A (x) = x ^ 2-6x + 9 #
#rArr A (x) = (x) ^ 2 - 2 * x * 3 + (3) ^ 2 #
#rArr A (x) = (x3) ^ 2 #
#rArr A (x) = (x - 3) (x - 3) #
Bunu not et
#color (kırmızı) a ^ 2 x ^ 2-bx + c ^ 2 = (sqrt (a ^ 2 x ^ 2) -sqrt (C ^ 2)) ^ 2 = (ax-c) ^ 2 # Nerede #b = 2ac #
