#10x^2-49x+18#

Explanation:

Using the distributive property:
#color(white)("XXX")color(red)(""(5x-2))color(blue)(""(2x-9))#

#color(white)("XXX")=color(red)(5x)color(blue)(""(2x-9))color(red) (-2)color(blue)(""(2x-9))#

#color(white)("XXX")=color(green)(10x^2-45x)color(purple)(-4x+18)#

#color(white)("XXX")=10x^2-49x+18#
