Question

2x²-x-1 reslove the following into factor​

Answer 1

Step-by-step explanation:

Given expression is 2x²-x-1

=>2x²-x-1

=>2x²-2x+x-1

=>2x(x-1)+1(x-1)

=>(x-1)(2x+1)

The factorization of 2x²-x-1 =(x-1)(2x+1)

Factors are =(x-1)(2x+1)=0

=>x-1=0 or 2x+1=0

X=1 and X=-1/2

Factors are 1 and -1/2

Answer 2

Answer:

the favtors are (x - 1)(2x + 1)

Step-by-step explanation:

doing middle term split

2x^2 - x - 1

2x^2 - 2x + x - 1

2x(x - 1) + 1(x - 1)

(x - 1)(2x + 1)
