Which of the following is a factor of 2x3 – 2?

x + 1

x2 + x + 1

x2 + 2x + 1

none of the above

The factor of:

                is:

We are asked to find the factor of  the algebraic expression which is given by:

we know that:

which could again be written by:

Since,. we know that:

Here a=1 hence,

Hence, the factors of:

are

               Hence, the answer is:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

here is a big fat
