solving (I)

⟹(x + 8)(x - 10)

Here this identify is used:-

⟹(x + a)(x - b) =  {x}^{2}  + (a + b)x + ab

⟹(x + 8)(x - 10) =  {x}^{2}  + (8 + ( - 10))x +  - 8 \times 10

⟹ {x}^{2}  - 2x  - 80 = 0

solving (ii)

⟹(x + 4)(x + 10)

⟹(x + 4) (x - 10) =  {x}^{2}  + (4 + ( - 10))x + 4 \times  - 10

⟹ {x}^{2}  - 6x - 40 = 0
