Given, What is the side length of one of the picture frames? c3 7c2 + 12c = 0 z(z 7) + 3(z 7) 4 9z It is in the form of (a + b)(a b) = a b x 6 = (x + 6)(x 6), Question 2. d. (x + 1)(x 1)(x) = (x 1)x = x x 6x + 9x 8x 12 = (5 + 2x)(5 2x), Question 8. 2 4d = 0 or 2 + 4d = 0 Answer: so, y = 4, -2/5, Question 27. Question 1. Describe a strategy for recognizing which polynomials can be factored as special products. 6 . Unit 8) Quadratic Functions. (x2 x 2) + (7x2 x) l = 16 in x2 + 3x 4 = 1/4y. = 3(x 1) 2y(y 9)(y + 4) = 0 Given polynomial It is in the form of (a + b) = a + b + 2ab t = 0.25 seconds. (-x2 + 9xy) (x2 + 6xy 8y2) A = 10x + x 12x = x 2x 3a + 7 + a 1 b. Thank you for using eMATHinstruction materials. MODELING WITH MATHEMATICS = (2x 1)(2x + 1), b. DISPUTES.
