Question

решите уровнение
(x-6)^2-x(x+8)=2​

Answer 1

Объяснение:

$(x - 6) {}^{2} - x(x + 8) = 2 \\x^{2}-12x+36-x\left(x+8\right)=2 \\x^{2}-12x+36-\left(x^{2}+8x\right)=2 \\x^{2}-12x+36-x^{2}-8x=2 \\-12x+36-8x=2 \\-20x+36=2 \\-20x=2-36 \\-20x=-34 \\x= -34:(-20)\\x = \frac{17}{10} = 1\frac{7}{10} = 1.7$
