Question

find whether or not the second polynomial is a factor of the first is x^2-4,x+2​

Answer 1

Answer:

Yes. it is.

Step-by-step explanation:

$x^{2} - 4 = 0$

Let,

${x}^{2} - {2}^{2} = 0 \\ \\ using \: {a}^{2} - {b}^{2} = (a + b) \times (a - b) \\ we \: get \\ (x + 2)(x - 2) = 0$

Therefore, x+2 is a factor of the given equation
