=color(blue)(24x^2 -31x +10=24x2−31x+10

Explanation:

color(blue)((3x−2))(8x−5)(3x−2)(8x−5)

=color(blue)((3x))*(8x) +color(blue)((3x)) . (-5) + (-color(blue)(2)) . (8x) + (-color(blue)(2)). (-5)(3x)⋅(8x)+(3x).(−5)+(−2).(8x)+(−2).(−5)

=24x^2 -15x -16x +10=24x2−15x−16x+10

=color(blue)(24x^2 -31x +10=24x2−31x+10
