expand (t+y-3w)(t+y+3w)

expand

(t + y - 3 w) (t + y + 3 w)

t^{2} + 2 t y + y^{2} - 9 w^{2}

Solution steps

(t + y - 3 w) (t + y + 3 w)

Distribute parentheses

= tt + t y + t \cdot 3 w + y t + yy + y \cdot 3 w - 3 wt - 3 w y - 3 w \cdot 3 w

Simplify

tt + t y + t \cdot 3 w + y t + yy + y \cdot 3 w - 3 wt - 3 w y - 3 w \cdot 3 w : t^{2} + 2 t y + y^{2} - 9 w^{2}

= t^{2} + 2 t y + y^{2} - 9 w^{2}

(- 3 ab - 8 a) - (- 5 a - 6 ab)
