Question

(x-5)²+(x-4)²=2x²
x=?

Answer 1

$(x - 5) {}^{2} + (x - 4) {}^{2} = 2x {}^{2} \\ x {}^{2} - 10x + 25 + x {}^{2} - 8x + 16 = 2x {}^{2} \\ 2x {}^{2} - 18x + 41 = 2x {}^{2} \\ - 18x + 41 = 0 \\ - 18x = - 41 \\ x = \frac{41}{18} \\ x = 2 \frac{5}{18}$
Ответ: х= 2 5/18
P.s. рад был помочь.

Answer 2

x²-10x+25+x²-8x+16=2x²
-18x+41=0
18x=41
x=41/18
$x = 2 \frac{5}{18}$
