Question

Find the product of (5x-2),(2x-3) and (3x-1) and verify the result for x=2.​

Answer 1

Step-by-step explanation:

(5x -2) (2x -3) (3x -1)

(10x 2-15x - 4x+6) (3x -1)

(10x 2 - 19x + 6) (3x -1)

30x3 - 10x2 - 57x 2 + 19x - 18x -6

30x3 -67 x 2 x -6

30(2) 3 -67 (2) 2 + 2 -6

30(8) - 67 (4) -4

240 - 268 - 4

240 - 272
