1. Expand and simplify each expression, showing all their work. A) (a + 2) (a + 2) b) (X +3) (x – 3) 2. Simplify each expression, showing all their work. A) (3xy ^ 3) (2x ^ 3y) b) 2a (March 2 y ^ 2) – y ^ 2 (3 – y) These are Examples questions. : S I would appreciate to show you how you got the answer. Knowing the answer does not help me at all.
For the first set of problems, "Expand" multiplying them. Since the distribution of pairs of marriage: a) (a + 2) (a + 2) = a (a + 2) +2 (A +2) = a ² + 2a + 2a + 4 = a ² + 4a 4 b) (x +3) (x – 3) = x (x – 3) + 3 (x – 3) = x ² – 3x + 3x – 9 = x ² – 9 for the second set of problems, we multiply the constants (coefficients), then multiply the variables, add the exponents of which have the same basis: a) (3xy ^ 3) (2x ^ 3y) = (3) (2) [X ^ (1 +3) [y] ^ (3 +1)] = 6x ^ 4y ^ 4 b) distribute one hand, by multiplying the coefficients and exponents adding: 2a (2a ² + 3y) – ² and (3 – Y) = 4y ² + 6y ^ 3 – 3y ² + y ^ 3 combine like terms: = 7y ² ²!
