Question

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

Answer 1

Answer:

x+3 is not a factor

Step-by-step explanation:

if (x+3) is a factor,

then x=-3 will satisfy the equation.

therefore,x2+2x+3=

(-3)2+2(-3)+3

9-6+3

=6

since quadratic equations should be equal to 0 always,therefore x+3 is not a factor.
