جواب:
# AB + B = 12، 65/8 #
وضاحت:
# 10x ^ 2-x-24 = (Ax-8) (Bx + 3) #
# 10x ^ 2-x-24 = ABX ^ 2 + 3Ax-8Bx-24 #
# 10x ^ 2-x-24 = ABX ^ 2- (8B-3A) X-24 #
# AB = 10 #
# 8B-3A = 1،:. 8 بی = 1 + 3 اے، بی = (1 + 3 اے) / 8 #
# (A (1 + 3A)) / 8 = 10 #
# 3 اے ^ 2 + A-80 = 0 #
#A = (- 1 + -قرآن (1-4 (3) (- 80))) / 6 = (- 1 + -قدر 961) / 6 = (-1 +31) / 6 #
# A = 5، -16 / 3 #
# A = 5،:. بی = 2،:. AB + B = 10 + 2 = 12 #
# A = -16 / 3،::. بی = -15 / 8،::. AB + B = 10-15 / 8 = 65/8 #
