Solve: (5x - 3y + 2z)²

Mathematics
1 answer:
gavmur [86]2 years ago
4 0

Answer:

25x^{2} - 30xy + 20xz + 9y^{2}  - 12yz + 4z^{2}

Step-by-step explanation:

We multiply it out.

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

5x*5x + 5x*-3y + 5x*2z - 3y*5x - 3y*-3y -3y*2z + 2z*5x +2z * -3y +2z *2z

25x^{2} - 15xy + 10xz - 15xy + 9y^{2} - 6yz + 10xz - 6yz + 4z^{2}

Add like terms

25x^{2} - 15xy - 15xy + 10xz + 10xz + 9y^{2} - 6yz - 6yz + 4z^{2}

25x^{2} - 30xy + 20xz + 9y^{2}  - 12yz + 4z^{2}
