Answer:
To multiply the expressions (3x+2y+1) and (2x-3y-5) vertically, you can use the distributive property and follow these steps:
1. Start by multiplying the first term in the first expression, 3x, by each term in the second expression:
- (3x) * (2x) = 6x^2
- (3x) * (-3y) = -9xy
- (3x) * (-5) = -15x
2. Move on to the second term in the first expression, 2y:
- (2y) * (2x) = 4xy
- (2y) * (-3y) = -6y^2
- (2y) * (-5) = -10y
3. Finally, multiply the last term in the first expression, 1, by each term in the second expression:
- (1) * (2x) = 2x
- (1) * (-3y) = -3y
- (1) * (-5) = -5
Now, let's combine the like terms:
6x^2 + (-9xy) + (-15x) + 4xy + (-6y^2) + (-10y) + 2x + (-3y) + (-5)
Simplifying this expression further, we have:
6x^2 - 5x - 9xy + 4xy - 6y^2 - 10y + 2x - 3y - 5
Therefore, the result of multiplying (3x+2y+1) and (2x-3y-5) vertically is 6x^2 - 5x - 9xy + 4xy - 6y^2 - 10y + 2x - 3y - 5.
