Math Problem Statement
Solution
The image you uploaded contains a set of algebraic problems related to expanding and simplifying expressions. Let's go over the steps for each one of the problems:
-
Expand and simplify. a)
To expand:
= x^2 + 6x + 2x + 12 = x^2 + 8x + 12$$ b) $$(x + 2)(x - 4)$$ To expand: $$(x + 2)(x - 4) = x(x - 4) + 2(x - 4) = x^2 - 4x + 2x - 8 = x^2 - 2x - 8$$ c) $$(3x + 1)(x - 2)$$ To expand: $$(3x + 1)(x - 2) = 3x(x - 2) + 1(x - 2) = 3x^2 - 6x + x - 2 = 3x^2 - 5x - 2$$ d) $$(x - 2)^2$$ To expand: $$(x - 2)^2 = (x - 2)(x - 2) = x(x - 2) - 2(x - 2) = x^2 - 2x - 2x + 4 = x^2 - 4x + 4$$ -
Write a simplified expression for the area of the figure. The figure might represent a rectangle or another geometric shape. Without seeing the actual figure, I can't provide the exact expression. Could you describe it for me? This will help me give you a more accurate solution.
