Question

Answer 1

Answer:

closed inputs on the number line

Step-by-step explanation:

$x^2=36\\x=6 \\x=-6$

Answer 2

Answer:

x=6,-6

Step-by-step explanation:

1) since both x^2 and 36 are perfect squares we can turn this into "a difference of perfect squares equation" by bringing 36 to the left

x^2-36=0

now we can split x^2 as

(x   ) (x  )

we can split -36 as:

(x-6) (x+6)

x-6=0

x=6

x+6=0

x=-6
