Answer 2

Sure, I can help you expand these expressions. Here's the expansion for each of the expressions you provided:

1. $(5+3x)(2x-7)$ expands to $10x^2 - 35x + 6x - 21$, which simplifies to $10x^2 - 29x - 21$.

2. $(x+2)(y-6)$ expands to $xy - 6x + 2y - 12$.

3. $(α+b)(4α-5b)$ expands to $4α^2 - 5ab + 4αb - 5b^2$, which can be simplified further.

4. $5y(y+5x-4)$ expands to $5y^2 + 25xy - 20y$.

5. $4x(x-5y+c)$ expands to $4x^2 - 20xy + 4cx$.

6. $(a - b)^2$ expands to $a^2 - 2ab + b^2$.

7. $(m - n)^2$ expands to $m^2 - 2mn + n^2$.
