expand (2x-3y-z+5)(2x-3y+z-5)

expand

(2 x - 3 y - z + 5) (2 x - 3 y + z - 5)

4 x^{2} - 12 x y + 9 y^{2} - z^{2} + 10 z - 25

Solution steps

(2 x - 3 y - z + 5) (2 x - 3 y + z - 5)

Distribute parentheses

= 2 x \cdot 2 x + 2 x (- 3 y) + 2 x z + 2 x (- 5) - 3 y \cdot 2 x - 3 y (- 3 y) - 3 yz - 3 y (- 5) - z \cdot 2 x - z (- 3 y) - zz - z (- 5) + 5 \cdot 2 x + 5 (- 3 y) + 5 z + 5 (- 5)

Simplify

2 x \cdot 2 x + 2 x (- 3 y) + 2 x z + 2 x (- 5) - 3 y \cdot 2 x - 3 y (- 3 y) - 3 yz - 3 y (- 5) - z \cdot 2 x - z (- 3 y) - zz - z (- 5) + 5 \cdot 2 x + 5 (- 3 y) + 5 z + 5 (- 5) : 4 x^{2} - 12 x y + 9 y^{2} - z^{2} + 10 z - 25

= 4 x^{2} - 12 x y + 9 y^{2} - z^{2} + 10 z - 25

\frac{2 + ( - 2 )}{2}

13 e \cdot 12.5

\frac{1}{12} \cdot 3

(- \frac{2}{2})^{2}

\frac{1}{x + 1} - \frac{2}{3}
