Answer 2

It seems like you've provided a list of algebraic expressions in the form of equations. However, I'm not sure what exactly you're asking for. It looks like you might want to solve these equations for the given variables. If that's the case, I can help you with that. Let's solve each equation step by step:

a) $Al \cdot (2y + 0.5)^2$ I'm not sure what "Al" represents here. If you mean a constant or a variable, please specify. If "Al" is a variable, then the expression would be: $Al \cdot (2y + 0.5)^2$.

b) $(-7x - 1)^2$ To square the expression, you need to multiply it by itself: $(-7x - 1)^2 = (-7x - 1) \cdot (-7x - 1) = 49x^2 + 14x + 1$.

в) $(a^2 - 2b)^2$ To square this expression, you need to multiply it by itself: $(a^2 - 2b)^2 = (a^2 - 2b) \cdot (a^2 - 2b) = a^4 - 4a^2b + 4b^2$.

г) $(8x + x^1)^2$ To square this expression, you need to multiply it by itself: $(8x + x^1)^2 = (8x + x)^2 = (9x)^2 = 81x^2$.

If you have any specific questions about these expressions or if you'd like to solve them for certain variables, please provide more information so I can assist you better.
