LOVELY SOLUTION MAAM

[@Maheshkumar-cw6un]

Very well done

[@satyadev3848]

perfect solution here

[@RealQinnMalloryu4]

{4x^2+6x^2}/9x^2=10x^4/9x^2= 1.1x^2=1^1.1^1x^2 1x^2 (x ➖ 2x+1).

When multiple on x-3, you need mark x#3.

[@SidneiMV]

x - 3 = u => x = u + 3 (u + 3)² + 3²(u + 3)²/u² = 16 (u + 3)²(1 + 9/u²) = 16 (u² + 6u + 9)(1 + 9/u²) = 16 u² + 6u + 9 + 9 + 54/u + 81/u² - 16 = 0 u² + 81/u² + 6u + 54/u + 2 = 0 (u² + 81/u²) + 6(u + 9/u) + 2 = 0 u + 9/u = t t² = u² + 81/u² + 18 u² + 81/u² = t² - 18 t² - 18 + 6t + 2 = 0 t² + 6t - 16 = 0 (t + 8)(t - 2) = 0 t = -8 u + 9/u = -8 u² + 8u + 9 = 0 u = (-8 ± 2√7)/2 u = -4 ± √7 => *x = -1 ± √7* t = 2 u + 9/u = 2 u² - 2u + 9 = 0 u = (2 ± i4√2)/2 u = 1 ± i2√2 => *x = 4 ± i2√2*
