Question

Factorise : 6x³- x² - 12x- 5​

Answer 1

Step-by-step explanation:

6x³-x²-12x-5

factors of 5 are -1,+1,-5,+5

p(-1) = 6(-1)³-(-1)²-12(-1)-5

= -6-1+12-5 = -7+7 = 0

take opposite of the -1

so, take x+1 as a divisor and divide with 6x³-x²-12x-5

by long division we will get 6x²-7x-5

=(x+1)(6x²-7x-5)

(x+1)(6x²+3x-10x-5)

=(x+1){3x(2x+1)-5(2x+1)}

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