Question

(3-5x) (8-3x) (2x+5) ​

Answer 1

Answer:

(3- 5x)(8-3x)

24 - 9x - 40x + 15x²

(24 -49x + 15x²)(2x + 5)

48x - 98x² + 30x³ + 120 -245 + 75 x²

48x - 98 x² + 75x² - 125 + 30x³

48x - 23 x² - 125 + 30x³

Answer 2

$1) = (3 - 5x)(8 - 3x)(2x + 5) \\ = (24 - 9x - 40x + 15 {x}^{2} )(2x + 5) \\ = (24 - 49x + 15 {x}^{2} )(2x + 5) \\=(48x-98{x}^{2}+30{x}^{3}+120-245x+75{x}^{2}) \\=30{x}^{3}-98{x}^{2} + 75 {x}^{2} + 48x - 245x + 120 \\ = 30 {x}^{3} - 23 {x}^{2} - 197x + 120 \: \: answer....$
