Найдите корень уравненияx=11x-12/x+4

X=11x12x+4

x=11x2+4x12x

Step 1: Multiply both sides by x.

x2=11x2+4x12

x2(11x2+4x12)=11x2+4x12(11x2+4x12)(Subtract 11x^2+4x-12 from both sides)

10x24x+12=0

x=bb24ac2a(Use quadratic formula with a=-10, b=-4, c=12)

x=(4)(4)24(10)(12)2(10)

x=449620

x=15+1531 or x=15+1531
