20n2+6n-2 (4n + 2)(5n -1)
This problem can be solved by FOILing. First, multiply the first terms to get 20n2
Next, multiply the outside terms to get -4n. Multiplication of the inside terms results in 10n. Combining -4n and 10n (they are like terms) is 6n. Then, multiply the last terms, to get -2. Combining these answers into one equation gives the answer of 20n2+6n-2.

7m2 + 6.5n - 4n + 2.5m2 - n = 9.5m2 + 1.5n
7 minus 2n equals 8n minus negative4n then what does N equal?
n=10/7. i did this one mentally. but are you sure its 8n minus negative 4n or is it 8n minus 4n? 8n- -4n does not equal 8n-4n 8n- -4n is the same as 8n+4n
What is 3n2 minus 5n minus 4n3 plus 5n2 plus n plus 7?
-4n3 + 8n2 - 4n + 7

-4n3 + 8n2 - 4n + 7
What is 4n plus 11 minus 7n equals negative 13?
-2.18
5n minus 11 equals 4n plus 20 What is n?
In the equation 5n-11=4n+20, n is equal to 31.
How do you factor 12n2 plus 5n minus 2?
(4n - 1)(3n + 2)
How do you solve 4n plus 13 equals n minus 8?
As follows:- 4n+13 = n-8 4n-n = -8-13 3n = -21 n = -7
What is 4n plus 1 times 2n plus 6?
(4n + 1)*(2n + 6) = 8n2 + 26n + 6
Six times a number minus five is less than twice the number plus ten?
Six times a number minus five is less than twice the number plus ten. 6 * n - 5 < 2 * n + 10 6n - 5 < 2n + 10 4n - 5 < 10 4n < 15 n < 15/4 This statement will hold true for all n < 15/4
How would you factor 12n squared plus 4n cubed minus 7n?
n(2n - 1)(2n + 7)
What is the number when 4 times the number plus 2 is equal to 8 times the number minus 16?
4n + 2 = 8n - 16 18 = 4n n =4.5 Check: 4 x 4.5 = 18, 18 + 2 = 20, 8 x 4.5 = 36, 36 - 16 = 20. QED
