w=x\left(-x\right)+40x-10\left(-x\right)-400
Whakamahia te āhuatanga tohatoha hei whakarea te x-10 ki te -x+40.
w=x\left(-x\right)+40x+10x-400
Whakareatia te -10 ki te -1, ka 10.
w=x\left(-x\right)+50x-400
Pahekotia te 40x me 10x, ka 50x.
w=x^{2}\left(-1\right)+50x-400
Whakareatia te x ki te x, ka x^{2}.
