1) xy = -4
2) x+y = 4
From (2), x = 4-y
Substitute into (1)
(4-y)y = -4
4y-y2 = -4
y2-4y-4 = 0
After using quadratic formula to solve this, you'll the values of y, which are 4.8284 and -0.8284 after rounding up.
If you use 4.8284 to substitude in (2) as y, your x value is -0.8284
Other if you use -0.8284, you'll get 4.8284
Therefore the two numbers are 4.828427125 and -0.828427124
They are: 11*11 = 121
103 is already prime.
The simplest answer for two numbers is 1 and 121. The most popular would be 11x11 however.
Yes it is. the two numbers will always have the same proportion to each other.
11.18033989 x 11.18033989
The numbers are: 30 and 5
They are: 2*3*11 = 66
1 x 871, 13 x 67.
97 is a prime number - therefore the only answer is 97 & 1
It depends on whether there are to be added, multiplied or something else. How about 1+2+157?
51 and 2
They are: 11*11 = 121
times the numbers by each other.
Multiplicand times multiplier equals product.
103 is already prime.
5 times 99 equals 495. There are several other answers.
Each of these factor pairs (multiply the numbers in parentheses) equals 106: (1, 106) (2, 53)
