Question

Решить пример (2y-x+12)*(-1,5y)

Answer 1

-2y × 1,5y - x × (-1,5y)-12×1,5y =  -3y^2 + 1,5 xy - 18y

Answer 2

To solve the expression, we need to apply the distributive property and simplify the result. Let's do the calculations step-by-step:

Expression: (2y - x + 12) * (-1.5y)

1. Distribute the -1.5y to each term inside the parentheses: -1.5y * 2y = -3y^2 -1.5y * -x = 1.5xy -1.5y * 12 = -18y

2. Combine the terms with the same variable: Final expression: -3y^2 + 1.5xy - 18y

So, the simplified expression is: -3y^2 + 1.5xy - 18y.
