Question

-10y(2y+3z)(3z-2y) помогите решить

Answer 1

-10y(2y+3z)(3z-2y)=(-20у²-30уz)(3z-2y)=-60y²z+40y³-90yz²+60y²z=40y³-90yz².

Answer 2

Simplifying the Expression

To simplify the expression -10y(2y+3z)(3z-2y), we can use the distributive property and combine like terms. Let's break it down step by step:

1. Start by multiplying the terms inside the parentheses: - 2y * 3z = 6yz - 2y * (-2y) = -4y^2 - 3z * 3z = 9z^2 - 3z * (-2y) = -6yz

2. Now, multiply the result from step 1 by -10y: - -10y * (6yz - 4y^2 + 9z^2 - 6yz) - Simplifying further, we get: - -60yz + 40y^2 - 90z^2 + 60yz

3. Combine like terms: - -60yz + 60yz = 0 - 40y^2 - 90z^2

Therefore, the simplified expression is 40y^2 - 90z^2.
