Homework SourseThe area of a rectangular barnyard is given by the trinomial
The area of a rectangular barnyard is given by the trinomial 6x^2 + 7x - 20. What are the possible dimensions of the barnyard? Use factoring. 2x-5 and 3x + 4 -2x + 5 and -3x + 4 2x + 5and 3x-4 2x-5 and 3x-4 18. The area of a rectangular picture frame is given by the trinomial 3X^2 - 9x - 30. What are the possible dimensions of the frame? Use factoring. (3x + 6) and (x - 5) (3x + 6)and(-x-5) (3x-6) and(x- 5) (3x-6) and (x + 5)
Solution
Solution:- 6x2 +7x -20
6x2 + 15 x - 8 x - 20 = 0
3x(2x + 5) - 4 (2x +5) = 0
(3x -4) ( 2x +5) =0
