Question

factorise using factor theorem 2x^3-x^2-7x+6​

Answer 1

Answer:

(x - 1) is the factor of 2x³ - x² - 7x +6

Step-by-step explanation:

suppose, (x-1) is the factor of given polynomial

to prove, and to factorise the polynomial

x-1=0 => x=1

we get, x = 1

now, putting the value of x in the given ploynomial 2x³-x²-7x+6 we have:

2(1)³-(1)²-7(1)+6

2-1-7+6 => 1 - 1 = 0

therefore, x - 1 is the factor of given ploynomial
