Question

i am not understand how x+1 is convert into p (-1)and x-1/2is convert into p (1/2) please solve first 2 question and explain me

Answer 1

x+1 = 0 , then
x = -1

x - 1/2 = 0, then
x = 1/2

just sifting no. so that we can get the value of x

Answer 2

Heya,

x+1 is converted to p(-1) and x-1/2 is converted to p (1/2) by using the formula -b/a where b= the constant and second term( here 1 and -1/2) and a= coefficient of variable term(here 1 as x has no coefficient)

1. x+1 so it is p(-1)  and -1 is substituted in place of x and p value is found.

2. Similarly x-1/2 so it is p ( -(-1/2) = p(1/2) and this 1/2 is substituted in place of x and p value is found.

Hope it helps u.......
