In can be less mental effort if the equation is multiplied by -1 first.
.. x^2 -10x +8 = 0
.. x^2 -10x +25 +8 -25 = 0
.. (x -5)^2 = 17
.. x -5 = ±√17
.. x = 5 ±√17

The values of x that satisfy the given equation are
.. x = 5 -√17 ≈ 0.877
.. x = 5 +√17 ≈ 9.123

Step-by-step explanation:

The given figure represent the theorem of circle,

It two chords of circle intersect outside or inside when produce, then

AP × PB = DP × PC

SO , from given data we can find the X

Now, (X + 4) × 4 = (9 + 3) × 3

Or, X + 4 = $\frac{12 times 3}{4}$

Or, X + 4 = $\frac{36}{4}$

Or, X = 9 - 4

∴ X = 5 unit
