Question

factorise 24x^3 - 64x^2- 21x + 56​

Answer 1

Required Answer:-

Given To Factorise:

• 24x³ - 64x² - 21x + 56

Solution:

We have,

24x³ - 64x² - 21x + 56

= 8x²(3x - 8) - 7(3x - 8)

= (8x² - 7)(3x - 8)

Note that this can't be factorised more.

★ Hence, the factorised form of the polynomial is (8x² - 7)(3x - 8)

Answer:

• The factorised form is - (8x² - 7)(3x - 8)
