Question

is x+2 a factor of 2x +4​

Answer 1

Step-by-step explanation:

yes, x + 2 is factor of 2x + 4

here,

2 ( x + 2 ) = 2x + 4

Answer 2

Step-by-step explanation:

QUESTION:

Prove that (x+2) is a factor of 2x+4.

SOLUTION:

If x+2 =0

Then, x = -2

∴ $f(x)$ = 2x+4

=> $f(x)$ = 2×(-2) +4

=> $f(x)$ = -4+4

=> $f(x)$ = 0

Since, (x+2) is equal to 0, so it is a factor of polynomial $f(x)$

HENCE, PROVED.
