Question

Can someone please solve these equations asap with step by step explanation you can also write an answer in the comments if u are unable to answer

1.7x × 2y - 4y × 3x
2.3x × 2x - 4y × 3y
3. (4x)(5x) - (5x)(4x)

Answer 1

`1.7x * 2x - 4y * 3x \\ 7x * 3x - 4y * 2y \\ 21x ^(2) - {8}y^(2) \\ 2.3x * 2x - 4y * 3y \\ 6x ^(2) - {12y}^(2) \\ 3.4x * 5x - 5x * 4x \\ {20x}^(2) - {20x }^(2) \\ 0`

Answer 2

If this helps you have to use the formula (x1,y1) and (x2,y2). So for number 1 it would be 7x - 3x and 2y - 4y
