lets go for the brakets first accourding top BDMAS rule (-x^2-6+3) the first braket here adition first -6+3=-3so we have -x^2-3 second one)-(-9x^2+x-1) its 9x^2-x+1 opening the brackets only opening the bracket of third one we get -x^2-5x+2 adding all -x^2-3+9x^2-x+1-x^2-5x+2 so taking common terms together -x^2+9x^2-x^2-x-5x-3+1+2 7x^2-6x thats the answer If you want me to solve it the it has got two roots x=0 and x=6/7
