Question

factorise the following by splitting the middle term .... x²-x-2​

Answer 1

Answer:

x=2 or -1

Step-by-step explanation:

=> x²-x-2

x²-x-2=> x²-2x+x-2

x²-x-2=> x²-2x+x-2=>x(x-2)+1(x-2)

x²-x-2=> x²-2x+x-2=>x(x-2)+1(x-2)=>(x-2)(x+1)

x²-x-2=> x²-2x+x-2=>x(x-2)+1(x-2)=>(x-2)(x+1)=>x-2 =0 |x+1=o

x²-x-2=> x²-2x+x-2=>x(x-2)+1(x-2)=>(x-2)(x+1)=>x-2 =0 |x+1=o =>x=2 | x=-1
