What is the square of n squared plus 2n minus 1?
(n2 + 2n - 1) (n2 + 2n - 1) = n4 + 2n3 - n2 + 2n3 + 4n2 - 2n - n2 - 2n + 1 = n4 + 4n3 + 2n2 - 4n + 1 try with n = 5: (5 squared + 10 - 1) squared = 34 squared = 1156 with formula (5^4) + (4 *(5^3)) + (2 * (5^2)) - (4 * 5) + 1 = 625 + 500 + 50 - 20 + 1 = 1156
What is the answer for 7n plus 6n-5 equals 4n plus 4?
n = 1 7n + 6n - 5 = 4n + 4 13n - 5 = 4n + 4 13n - 4n - 5 = 4n - 4n + 4 9n - 5 = 4 9n -5 + 5 = 4 + 5 9n = 9 n = 1
What is 2n squared plus 5n plus 2?
That factors to (2n + 1)(n + 2)
Twice the greater of two consecutive odd integers is 13 less than three times the lesser Find the integers?
The representation of an odd integer is 2n + 1. So the other consecutive odd integer will be 2n + 3,[(2n + 1) + 2]. Thus, we have:2(2n + 3) + 13 = 3(2n + 1)4n + 6 + 13 = 6n + 3 subtract 4n and 3 to both sides16 = 2n divide by 2 to both sides8 = n2n + 1 = 2(8) + 1 = 16 + 1 = 172n + 3 = 2(8) + 3 = 16 + 3 = 19Therefore, theses numbers are 17 an 19.Check:3(17) - 2(19) = 13 ?51 - 38 = 13?13 = 13 True
6 equals 1 - 2n plus 5?
6=(1-2n)+5 6-5=(1-2n)+5-5 1=1-2n 1-1=1-1-2n 0=-2n 0/-2=-2n/-2 0=n
Solve n for 12 plus 4n equals 2n?
12+4n = 2n12+4n-4n = 2n-4n12 = -2n-1/2(12 = -2n)-6 = n
What is 2n squared plus 4n?
If the given equation were factorized it would be: 2n2 + 4n = 2n(n+1) Another Answer:- The given expression when factored is 2n(n+2)
How would you factor 12n squared plus 4n cubed minus 7n?
n(2n - 1)(2n + 7)
What is the answer to 4n 1-23-2n?
If you mean: 4n = 1-23-2n then 6n = -22 and so n = 11/3
What is the answer to 23-4n?
If you mean: 4n = 1-23-2n then 6n = -22 and so n = 11/3
What is -2n plus 9n?
7n -1n,0n,1n,2n,3n,4n,5n,6n,7n 1 2 3 4 5 6 7 8 9
Why does an even number plus to odd number equal to odd?
Any even number can be written in the form 2n for some natural number n.Any odd number can be written as 2n+1 for a natural number nNow add an even to an odd.2n+2n+1=4n+1 which is 2(2n)+1 and this is the form for an odd number.
Five more than twice a number is three more than four times the number What is the number?
The question can be represented as the equation, 2n + 5 = 4n + 3 where n is the unknown number. 2n + 5 = 4n + 3 : subtract 2n from both sides 5 = 2n + 3 : subtract 3 from both sides 2 = 2n : divide both sides by 2 1 = n The unknown number has been identified as 1.
What is (-1)(2n)(4n)?
FOIL deals with polynumerals in math. An example is a difference of squares as in (2n - 2)2 or (2n + 2)(2n - 2) =F stand for first--2n X 2n = 4n2O stands for outside-- 2n X -2 = -4nI stands for inside-- -2 X 2n = 4nL stands for last--2 X -2 = -4In the end you get:4n2 - 4n + 4n - 4 = 4n2 - 4Can you see how everything is squared and the two numbers are being subtracted?
What is -8n plus 6 plus 4n-7?
It is an expression that can be simplified to -4n-1
What is 4n plus 13 equals 1?
4n+13=1 -13 -134n=-12/4 /4n=-3
What is the square of n squared plus 2n minus 1?
(n2 + 2n - 1) (n2 + 2n - 1) = n4 + 2n3 - n2 + 2n3 + 4n2 - 2n - n2 - 2n + 1 = n4 + 4n3 + 2n2 - 4n + 1 try with n = 5: (5 squared + 10 - 1) squared = 34 squared = 1156 with formula (5^4) + (4 *(5^3)) + (2 * (5^2)) - (4 * 5) + 1 = 625 + 500 + 50 - 20 + 1 = 1156
