Answer:
(x - 6)(x + 6) = 0
Step-by-step explanation:
This is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
Given
x² - 36 = 0, then
x² - 6² = 0
(x - 6)(x + 6) = 0 ← in factored form
Answer:
(x-6)(x+6) = 0
Step-by-step explanation:
x to the power of 2 minus 36.
6 squared is 36 so therefore. you must have 2 6's in the brackets somewhere.
then the 2 x's need to be there too.
another example can be.
x^2-81=0
it would be (x-9)(x+9)=0
you just always have the plus and minus int he brackets
