3n2 - 7n = 0
n(3n - 7) = 0
So either n = 0 or 3n-7 = 0
ie, either n = 0 or n = 7/3 = 21/3 = 2.33...

How do you solve 4n minus 7n equals 21?
4n - 7n = 21(4-7) n =21-3n = 21divide both sides by -3n = -7
What is 3n plus 9 equals 7n-15?
n=6
What is 3n squared minus 5n minus 4n cubed plus 5n squared plus n plus 7?
Assuming you meant 7n (not just 7 at the end of your question) - first... simplify the equation. Numbers raised to powers get priority - so your new sum is... 5n - 64n + 25n + n + 7n.... This simplifies to... -26n
What is 3n-9 plus 4n equals 8n?
3n - 9 + 4n = 8nCombine like terms:7n - 9 = 8nSubtract 7n from both sides:-9 = n
7n plus 2y-3n plus y equals?
4n + 3y
How do you solve 4n minus 7n equals 21?
4n - 7n = 21(4-7) n =21-3n = 21divide both sides by -3n = -7
What is 7n squared minus 7n?
7n(n−1)
7n - 2 plus 3n plus 4 equals?
7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)
What is 3n plus 9 equals 7n-15?
n=6
What is 7nĀ²-3n equals 0?
n(7n-3) = 0 n = 0 or n = 3/7
What is 3n squared minus 5n minus 4n cubed plus 5n squared plus n plus 7?
Assuming you meant 7n (not just 7 at the end of your question) - first... simplify the equation. Numbers raised to powers get priority - so your new sum is... 5n - 64n + 25n + n + 7n.... This simplifies to... -26n
What is 3n-9 plus 4n equals 8n?
3n - 9 + 4n = 8nCombine like terms:7n - 9 = 8nSubtract 7n from both sides:-9 = n
7n plus 2y-3n plus y equals?
4n + 3y
What is 7n-2 plus 3n plus 4 equals?
10n+2
What is the perimeter of 7n plus 2 plus 6 plus 5n plus 7n plus 3n equals?
22n + 2.
How do you multiply out 64m-3n 7n 3m?
(64m-3n)*7n*3m = 1344m2n - 63mn2
What is 7n - 2 plus 3n plus 4 simplfied?
Gather like terms. The - 2 and 4; the 7n and 3n. 7n - 2 + 3n + 4 = 10n + 2
