Which products result in a difference of squares or a perfect square trinomial? Check all that apply. (5x + 3)(5x – 3)(7x + 4)(7x + 4)(2x + 1)(x + 2)(4x – 6)(x + 8)(x – 9)(x – 9) (–3x – 6)(–3x + 6)
Which expressions can represent the length and width of the garden?
Louise completed the work shown below.(5x3 + 3)2 = (5x3)2 + (3)2 = 25x6 + 9Determine if Louise’s answer is correct. Explain.
Louise's answer is incorrect. When squaring a binomial, you must multiply the binomial by itself (5x^3 + 3)(5x^3 + 3). Using the FOIL method or the distributive property, the middle term is 2(5x^3 * 3) = 30x^3. Her result should have been 25x^6 + 30x^3 + 9. She incorrectly simply squared the individual terms instead of using the formula for a perfect square trinomial (a + b)^2 = a^2 + 2ab + b^2.
