    let's deal with the bracket first whenever u see negative sign outside the paretheses first you should use distributive property \[[(6x ^{2}+3x+2)\color{ReD}{-(3x ^{2}-4x+5)}]-(x ^{2}+4x-5)\] distribute parentheses by negative one

    \[[(6x ^{2}+3x+2)-(-3x ^{2}-4x+5)]-(x ^{2}+4x-5)\]

    let's deal with the bracket first whenever u see negative sign outside the paretheses first you should use distributive property \[[(6x ^{2}+3x+2)\color{ReD}{-(-3x ^{2}-4x+5)}]-(x ^{2}+4x-5)\] distribute parentheses by negative one

    so after distribution my equation looks like \[[6x ^{2}+3x+2+3x ^{2}+4x-5]-(x ^{2}+4x-5)\]

    right now combine like terms in the bracket and then distribute parentheses by negative one :=)

    so the answer I got was \[8x ^{2}+3x+8\]

    \[[\color{ReD}{6x ^{2}+3x+2+3x ^{2}+4x-5}]-(x ^{2}+4x-5)\] what are like terms in the bracket ?

    \[6x ^{2} + 3x ^{2} =9x ^{2}, 3x + 4x =7x , 2+ (-5) =3\]

    hmme 2 +(-5 ) isn't positive 3 remember if the bigger number is negative then answer would be negative :=)
