Factorising, we obtain,
x2 + 10x + 21 = (x + 7)(x + 3).
Thus,
x2 + 10x + 21 / (x + 3) = x + 7.
That's usually easier than dividing it out!

X2 plus 10x plus 21 by x plus 3?
(x2+10x+21)/(x+3) = (x+7)
What is X2 plus 10x plus 21 equals?
x2 + 10x + 21 = (x + 3)(x + 7)
What is the answer for 2x - 3 equals 21 plus 10x?
2x-3 = 21+10x 2x-10x = 21+3 -8x = 24 x = -3

21
What is the factorization of x2 plus 10x plus 21?
x2 + 10x + 21 = (x + 3)(x + 7) You need to find 2 numbers which sum to 10 and whose product of 21. In this case 3 + 7 = 10 and 3 x 7 = 21.

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y2 of (x + y) 2. There is, for example, no operator between 2 and 10X.
What is the answer for 2x - 3 equals 21 plus 10x?
2x-3 = 21+10x 2x-10x = 21+3 -8x = 24 x = -3
