Question

Factorise 2x cube minus 3 x spuare minus 17 X + 30​

Answer 1

hello,

here is your answer:

**********

2x³ - 3x² - 17x + 30

(2x³ - 3x²) (- 17x + 30)   [group the terms]

(2×x×x×x - 3×x×x) (1×-17×x + 1×30)   [find common factors]

x² (2x - 3) 1 (-17x + 30)   [separate the common factors]

ans: x² (2x - 3) 1 (-17x + 30)

You can verify the answer by multiplying it, you should be able to get the expression we started with (2x³ - 3x² - 17x + 30).
