Question

РЕШИТЕ (x-2)^2=3(x-2)

Answer 1

${(x - 2)}^{2} = 3 times (x - 2) \ {x}^{2} - 4x + 4 = 3x - 6 \ {x}^{2} - 4x - 3x + 4 + 6 = 0 \ {x}^{2} - 7x + 10 = 0 \ a = 1 \ b = - 7 \ c = 10 \ d = { - (b)}^{2} - 4 times a times c = - 49 - 40 = - 89 \ x 1= frac{ 7 + sqrt{89}}{2} = 3.5 + sqrt{89} \ x2 = frac{7 - sqrt{89} }{2} = 3.5 - sqrt{89}$
