What is the LCM of 10x and 42x?
210x
How do you factor x2-10X plus21?
(x - 7)(x - 3)
What is the LCM of x2 plus 8x 9 and x2 1?
x2 + 8x - 9 factors to (x - 1)(x + 9) x2 - 1 factors to (x - 1)(x + 1) The LCM will be (x - 1)(x + 1)(x + 9) or x3 + 9x2 - x - 9 The GCF is (x - 1)
Factor completely the given polynomial x x plus 19 plus 10 x plus 19?
If the polynomial is meant to be x2 + 19 + 10x + 19 then there is no real factorisation. x2 + 19 + 10x + 19 = x2 + 10x + 38 has no real roots and so no real factorisation. Limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible for me to be sure that I have answered the question that you meant to ask. If the polynomial was meant to be something else, please resubmit the question spelling out the symbols as "plus", "minus", "times", "equals", "squared", "cubed" etc. Also, please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y2 of (x + y) 2.
What are the factors of 100x2 plus 20x 1?
If that's + 1, the answer is (10x + 1)(10x + 1) or (10x + 1)2 If that's -1. it gets ugly in a hurry.
