    How do I factorise quickly instead of using trial and error?

    28x? - 19x = 20 x? - 19/56x = 5/7 + (- 19/56)? x? - 19/56x = (2,240 + 361)/3,136 (x - 19/56)? = 2,601/3,136 x - 19/56 = ? 51/56 = x - 19/56 - 51/56, = x - 70/56, = x - 5/4, = 4x - 5 = x - 19/56 + 51/56, = x + 32/56, = x + 4/7, = 7x + 4 Answer: (4x - 5)(7x + 4)

    the length of a rectangular garden is 3yd more than twice its width. the perimeter

    Width—w: 2(w + 2w + 3) = 36 3w + 3 = 18 w + 1 = 6 w = 5 Length: = 2(5) + 3 = 10 + 3 = 13 Answer: 5 yd is the width, 13 yd is the length

    rectangle garden 4' wide, garden 2'longer than width, path way 224 square',

    Answer: width, 4 ft; length, 6 ft (4 + 2) are the garden's dimensions. Pathway width (x): (x + 4)(x + 6) - (4 * 6) = 224 x² + 6x + 4x + 24 - 24 = 224 x² + 10x = 224 x² + 5x = 224 + 5² x² + 5x = 224 + 25 (x + 5)² = 249 x + 5 = 15.779734 x = 10.779737 Answer: 10.779737 feet are the width of the...
