Jawapan:
#color (magenta) (=> x = -1 #
Penjelasan:
# (x-2) ^ 2 + 3x-2 = (x + 3) ^ 2 #
Menggunakan Identiti:
#color (merah) (=> (a-b) ^ 2 = a ^ 2-2ab + b ^ 2 #
#color (merah) (=> (a + b) ^ 2 = a ^ 2 + 2ab + b ^ 2 #
Kami ada, # x ^ 2-2 (x) (2) + 2 ^ 2 + 3x-2 = x ^ 2 + 2 (x) (3) + 3 ^ 2 #
# => cancelx ^ 2-4x + 4 + 3x-2 = cancelx ^ 2 + 6x + 9 #
# => - 4x + 4 + 3x-2 = 6x + 9 #
# => - 4x + 3x-6x = 9-4 + 2 #
# => - 7x = 7 #
# => x = -7 / 7 #
#color (magenta) (=> x = -1 #
~ Harap ini membantu!:)
