Question

use factor therom of determine whether ( x + 3 ) is factor of x2+2x-3 or not.​

Answer 1

Answer:

Let p(x) = x2 + 2x − 3. So, by factor theorem, (x + 3) is a factor of x2 + 2x − 3.

Answer 2

Step-by-step explanation:

if (x+3) is factor then the value of x=(-3)

now we solve the equation by putting the value of x=(-3)

if the solution is zero then x+3 is a factor other wise not

let's solve it

=(-3)²+2(-3)-3

=9-6-3

=9-9

=0

hence it is a factor

hope it will help uhh
