There could be a few values. 45 divided by 1 could work, and X=root 45 and Y=1
There are two variables, so two equations would be needed to determine the values. Otherwise, there are many solutions.
4
If x = 8 then x2 = 82 = 8 x 8 = 64
We can't calculate what it equals until we know the value of ' x '.
x2 + 2y = 52 + 2*2 = 25 + 4 = 29
x2 + 14x + 45 = 0 => x2 + 9x + 5x + 45 = 0 => x(x + 9) + 5(x + 9) = 0 (x + 9)(x + 5) = 0 so that x = -5 or x = -9
if x2 = 5 the value of x has to be 5 divided by 2 which is 2.5 x = 2.5
4
If x = 8 then x2 = 82 = 8 x 8 = 64
We can't calculate what it equals until we know the value of ' x '.
x2 + 2y = 52 + 2*2 = 25 + 4 = 29
"x2 = 100" is an equation which, if solved for x, will give you two possible value: 10 and -10.
x2 + 14x + 45 = 0 => x2 + 9x + 5x + 45 = 0 => x(x + 9) + 5(x + 9) = 0 (x + 9)(x + 5) = 0 so that x = -5 or x = -9
x2 / y = (6)2 /2 = 36/2 = 18
You need to know the value of x
x=5/2 or 2.5
8
x2 + x2 = 2x2
