Given Equation is √3x^2 + 11x + 6√3 = 0

⇒ √3x^2 + 9x + 2x + 6√3 = 0

⇒ √3x(x + 3√3) + 2(x + 3√3) = 0

⇒ (√3x + 2)(x + 3√3) = 0

⇒ x = -2/√3, -3√3.

(2)

Given Equation is 3x^2 - 2√6x + 2 = 0

⇒ 3x^2 - √6x - √6x + 2 = 0

⇒ √3x(√3x - √2) - √2(√3x - √2) = 0

⇒ (√3x - √2)(√3x - √2) = 0

⇒ x = √2/√3, √2/√3.

To Find:-

9(x + 11) + 2(x + 7) - 25 = 5(x + 2) + 7(x - 3) - 20

Solution:-

9(x + 11) +  2(x + 7) - 25 = \\  5(x + 2) + 7(x - 3) - 20 \\  =  > 9x  + 99 + 2x + 14 - 25 \\  = 5x + 10 + 7x - 21 - 20 \\  =  > 11x + 88 = 12x - 31 \\ 11x + 119 = 12x \\ 12 x - 11x = 119 \\ x = 119

Value of x = 119

Verification:-

 =  >  9(119 + 11) + 2(119 + 7) - 25  \\ =  5(119 + 2) + 7(119 - 3) - 20 \\  =  > 9(130) + 2(126) - 25 \\  = 5(121) + 7(116) - 20 \\ 1170 + 252 - 25 = 605 + 812 - 20 \\ 1170 + 227 = 605 + 792 \\ 1397 = 1397

L.H.S=R.H.S

hence verified
