Why not just plug it in? You could find the square, cube, and so on; or use a method that just requires repeated multiplication, if you have learned that.Hello,
I got this problem where I could get the x value after simplifying. However, I cannot manipulate the given expression to utilize the x value.
I would appreciate any help on this. Thanks.
Is this question part of an exercise in which the other questions all simplify in some specific way?Hello,
I got this problem where I could get the x value after simplyfying. However, I cannot manipulate the given expression to utilize the x value.

Thanks for the advice. Plugging in would be quite a labor-intensive exercise. I am trying to figure out if it can be done in a shorter way.Why not just plug it in? You could find the square, cube, and so on; or use a method that just requires repeated multiplication, if you have learned that.
You might carry out the polynomial division before doing so.
And it might help to find a quadratic of which x is a zero.
But what you've done so far is correct, if that helps.
I don't see any shorter way. Before that excercize, I would make sure that the coefficients and the 'signs' are correct.Thanks for the advice. Plugging in would be quite a labor-intensive exercise. I am trying to figure out if it can be done in a shorter way.
It isn't hard at all, if you do what I suggested. Have you tried at all?Thanks for the advice. Plugging in would be quite a labor-intensive exercise. I am trying to figure out if it can be done in a shorter way.
