= 1/x+1 + 2/x+2 = 4/x+4
= x +2 + 2(x+1)/(x+1)(x+2) = 4/x+4
= x + 2 + 2x + 2 / x^2 + x + 2x + 2 = 4/x+4
= 3x + 4 / x^2 + 3x + 2 = 4/x+4
= (x+4)(3x+4) = 4(x^2 + 3x + 2 )
= 3x^2 + 12 x + 4x + 16 = 4x^2 + 12x + 8
= x^2 - 4x - 8 = 0
D = b^2 - 4ac
= 16 - 4(-8)(1)
= 16 + 32
= 48
√D = √48
=√2×2×2×2×3
= 4√3
x = -b + √D/2a or -b - √D/2a
= 4 + 4√3 / 2 or 4 - 4√3 / 2
= 2 (1+√3) or 2(1-√3)
