Question

Multiply the factors with full solution each.

1. 3x (2x - 5)
2. (x + 2y)squared
3. (x - 3) (x + 2)
4. (3x + 2y) (x + 3y)
5. (x - 4) (x + 4)​

Answer 1

Step-by-step explanation:

1. 3x(2x-5)

6x²-15x

2. (x+2y)²

use the property (a+b)² = a²+2ab+b²

x²+4xy+4y²

3. (x-3)(x+2)

x(x+2)-3(x+2)

x^2+2x-3x-6

x²-1x-6

4. (3x+2y)(x+3y)

3x(x+3y)+2y(x+3y)

3x²+9xy+2xy+6y²

3x²+11xy+6y²

5. (x-4)(x+4)

in this u have to use a property (a+b)(a-b) = a²-b²

so

(x)²-(4)²

x²-16

hope this helps
