Question

use the identity (x+a) (x + b) = x² + (a+b)x+ab to find the value of (p-1/2)×(p-1/5)​

Answer 1

Answer:

p^2+(-7/10)p+(1/10)

Step-by-step explanation:

[p+(-1/2)]*[p+(-1/5)]=p^2+[(-1/2)+(-1/5)]p+(-1/2)(-1/5)

                             =p^2+[(-5-2)/10]p+(1/10)

                               =p^2+(-7/10)p+(1/10)
