Hey Lackinmath, you ain't "lackin" this time. You're absolutely right!
3{2[4(x^2+2)-2(x^2-5)]}
3{2[4(x^2)+4(2)-2(x^2)-2(-5)]}
3{2[4x^2+8-2x^2+10]}
3{2[4x^2-2x^2+8+10]}
3{2[2x^2+18]}
3{2(2x^2)+2(18)}
3{4x^2+36}
3(4x^2)+3(36)
12x^2+108
You're gonna have to change your name to something like lotsamath or something!!!
Happy Calculating!!!
