Solve (4x - 7y z) (-4x - 7y^3z)

Evaluate

(4 x - 7 yz) (- 4 x - 7 y^{3} z)

Apply the distributive property

4 x (- 4 x) - 4 x \times 7 y^{3} z - 7 yz (- 4 x) - (- 7 yz \times 7 y^{3} z)

Multiply the terms

More Steps

- 16 x^{2} - 4 x \times 7 y^{3} z - 7 yz (- 4 x) - (- 7 yz \times 7 y^{3} z)

Multiply the numbers

- 16 x^{2} - 28 x y^{3} z - 7 yz (- 4 x) - (- 7 yz \times 7 y^{3} z)
