Translate to an equation:
x + x2 = 30
Solve for x:
x2 + x - 30 = 0
(x + 6)(x - 5) = 0
x = 5, -6

The average of a set of numbers is defined as the sum of those numbers divided by the number of numbers. If the average is given, multiply that by number of items in the set including the missing number. Subtract the sum of given numbers from this quotient and the missing number is revealed.
To find the third number, we first need to subtract the sum of the two known numbers (29854 + 17031) from the total sum of 83095. This gives us 36210. Since the third and fourth numbers are the same, we divide 36210 by 2 to find the value of each of these numbers. Therefore, the third number is 18105.
The numbers are 21 and 63.
example for sum of rational numbers is 1/3 + 1/5 Example for sum of irrationals is Pi + e where e is is base of natural log Another is square root of 2 + square root of 3.
The formula for finding the nth square number is n^2. Therefore, the 3rd square number is 3^2 = 9, and the 6th square number is 6^2 = 36. To find the sum of the 3rd and 6th square numbers, you add them together: 9 + 36 = 45. So, the sum of the 3rd and 6th square numbers is 45.
Sum of squares? Product?
There are two solution: -3 and +2.
There aren't any whole numbers that satisfy this.
= The sum of two numbers is -42 the first number minus the second number is 52 Find the numbers? =
You can. Just add the numbers together, and find their square root. One plus three is four; the square root of the sum is two.

The number is 7.
The average of a group of numbers is equal to the sum of the numbers divided by the number of numbers. If you want to find the sum of the five numbers, just multiply 790.6 by 5 to get the sum, which is 3953
25 (32 + 42 = 52)
N squared would be used to find the square root of a number or numbers. In order to find the number of three digit numbers such that the sum of the square results of any two digits are equal to the third digit the use of the formula (HOE)squared=Hsquared*10000+2HE*100+Esquared is needed.
