Answer:

yes

Step-by-step explanation:

let x-3 is it's factor

so, x-3=0

x=3

p(x)=x^2 +2x -15

p(3)= 3^2 + 2(3)-15

= 9+6-15

=0

the remainder is zero it means that our supposition is right

x-3 is its factor.....

if (x-3) is the factor of x^2+2x-15=0 then it will satisfy the equation

x-3=0

x=3

f(x)=x^2+2x-15

f(3)=3^2+2(3)-15

f(3)=9+6-15

f(3)=15-15=0

hence (x-3) is the factor of above equation
