Question

please find me a value of x​

Answer 1

Answer:

(1 - x)² = 2x²

(a - b)² = a² -2ab + b²

1² -2×1× x + x² = 2x²

transposing x² to RHS

1 -2x + x² = 2x²

1 - 2x = 2x² - x²

1 - 2x = x²

Underroot 1 - 2x = x

HOPES THIS HELPS YOU.......

Answer 2

(1-x)^2=2x

1-2x+x^2=2x. 1-2x+x^2-2x=0 1-4x+x^2=0. x^2-4x+1=0. x=-√-(-4) +_√(-4)^2-4×1×1/2×1. next x=4+-√16-4/2. x=4+-√12/2. x=4+-2√3/2. x=4-2√3/2 x=4+2√3/2. x=+2√3. x=-2√3
