Question

2. (x+8) (x-10) sove using identities
​

Answer 1

Answer:

$(x + 8)(x - 10) = {x}^{2} - 2x - 80$

note that,

$(x +2 y)(x - y) = {x}^{2} - xy +2 xy - 2{y}^{2}$

this is your answer hope it helps to you☺️

Answer 2

The identity we are using is (x+y)(x+z)=x^2 + (y+z)x + (yz)

In this case... x^2 + (8-10)x + (8*-10)
= x^2 - 2x - 80

Hope it helps...
