x^2 +2x - 8 = 0

(x - 2) ( x + 4) = 0

x = 2, x = - 2

(x - 2) ( x + 4) = 0

x = 2, x = - 2

(d^2+d-30)/(d^2+3d-40) + (d^2+14d+48)/(d^2-2d-48)

= (d - 5)(d + 6)/(d + 8)(d - 5) + (d + 6)(d + 8)/(d - 8)(d + 6)

= (d + 6)/(d + 8) + (d + 8)/(d - 8)

= (d + 6)(d - 8)/(d + 8)(d - 8) + (d + 8)(d + 8)/(d - 8)(d + 8)

= (d^2 - 2d - 48)/(d + 8)(d - 8) + (d^2 + 16d + 64)/(d + 8)(d - 8)

= (2d^2 + 14d + 16)/(d + 8)(d - 8)

= (d - 5)(d + 6)/(d + 8)(d - 5) + (d + 6)(d + 8)/(d - 8)(d + 6)

= (d + 6)/(d + 8) + (d + 8)/(d - 8)

= (d + 6)(d - 8)/(d + 8)(d - 8) + (d + 8)(d + 8)/(d - 8)(d + 8)

= (d^2 - 2d - 48)/(d + 8)(d - 8) + (d^2 + 16d + 64)/(d + 8)(d - 8)

= (2d^2 + 14d + 16)/(d + 8)(d - 8)
