=#9#

There is obviously a small typing error in the question....

Let's assume it is supposed to read:

#color(blue)(30)color(magenta)(-[9+4(8-5)])" there are two terms"#

Work from the inside bracket .

=#color(blue)(30)color(magenta)(-[9+4(3)])#

=#color(blue)(30)color(magenta)(-[9+12]#

=#color(blue)(30)color(magenta)(-[21])#

=#9#
