Let's simplify those expressions first! For the first set of equations: - A can be simplified as \( A = 5x + 20 \). - B simplifies to \( B = 14x - 35 + 3x + 6 = 17x - 29 \). - C expands to \( C = (x + 2)(3x - 5) = 3x^2 + 6x - 5x - 10 = 3x^2 + x - 10 \). Now, regarding the second set for factoring: - For D, we can factor out the common factor: \( D = 4(x + 5) \). - For E, we can reorganize and factor it to get \( E = y(2x + 12xz) - 19z \) or factor differently depending on desired outcomes. - For F, notice that there’s a common term: \( F = (2x + 1)(3 - 4) = (2x + 1)(-1) = -2x - 1 \). And voila! Your equations are simplified and factored. Keep practicing to make it even easier!
