Question

write the X² - 1 as the product of two first degree polynomials​

Answer 1

We Know that,

(a)²-(b)²= (a+b) (a-b)

P(x)= x²= 9

P(x)= (x)²= (3)²

P(X)= (x+3) (x-3)

So the answer is, (x)²-9= (x+3) (x-3)

Hope it helps you to mark me as a brainiest.

Answer 2

We must recall that:

An algebraic expression (or) a variable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc

Given: $x^2-1$                       ........ (1)

we know $a^2-b^2=(a+b)(a-b)$           ......... (2)

compare equation $1$ and $2$, we get

$x=a,b=1$

Therefore, $x^2-1=(x+1)(x-1)$
