To solve, eliminate the exponent 2. So, take the square root of both sides.
Then, isolate x. To do so, add both sides by 2.3.
And, compute for the values of x.
`x=5+2.3=7.3 ` and `x=-5+2.3=-2.7`
Hence, the solutions are `x=-2.7` and `x=7.3` .
I assume the problem is:
(x-2.3)^2 = 25
There are a couple of ways to do this problem. The way I would do it is, first, take the square root of each sides. That gives you:
x-2.3 = +-5, meaning positive 5 and negative 5.
For this, we separate the equation into two equations:
x-2.3 = 5 and x-2.3 = -5
Solving these, we add 2.3 to all sides, giving us:
x = 7.3 x = -2.7
So, there would be two solutions.
Good Luck, user5932103. I hope this helps.
