Question

the value of p in (x-5)(x-2) = x^2+px +10 is

Answer 1

Answer:p=1

Step-by-step explanation:Given : (1)

Let -5 =a and 6=b

Then by using identity : , we have

Substituting the value of in (1), we get

On comparing the coefficient of x , we get

p=1

Answer 2

Answer:

x= -7

Step-by-step explanation:

(x-5)(x-2) =x square+px+10

or,x square-2x-5x+10=x square+px+10

or,x square-7x+10= x square+px+10

or x= -7(If all are matched with each other by side by side,so,the p is -7..)
