Question

Polynomials x2-9=0 solve w steps

Answer 1

solving the polynomial $x^2-9=0$ we get x = -3 and x= 3

Step-by-step explanation:

we need to solve the polynomial:

$x^2-9=0$

The polynomial can be written as:

$(x)^2-(3)^2=0$

Using the formula: a^2-b^2= (a+b)(a-b)

$(x)^2-(3)^2=0\\(x-3)(x+3)=0\\x-3=0\,\,and\,\,x+3=0\\x=3\,\,and\,\,x=-3$

So, solving the polynomial $x^2-9=0$ we get x = -3 and x=3
