Question

solve the factor of x square - 36

Answer 1

x²-36
= (x)²-(6)²
= (x+6)(x-6) [a²-b² = (a+b)(a-b)]

Answer 2

Answer:

-6 and 6 are the required roots of the given equation .

Step-by-step explanation:

Explanation:

Given , $x^2$ - 36

By the help of difference square formula we  can solve the given equation .

$a^2 - b^2$ is known as difference squares formula .

And $a^2 - b^2$ = (a+ b)(a- b)

Step 1:

The given equation is  $x^2$ - 36 .

By the help of  formula ($a^2 - b^2$) we can written the given equation as ,

$x^2$ - 36  = $x^2 - 6 ^2$                     [6 ×6 = 36 ]

⇒ $x^2 - 6 ^2$ = (x+6)(x- 6)

Therefore , x + 6 = 0 and x - 6 = 0

⇒ x = -6 , 6

Final answer :

Hence , the value roots of the equation $x^2 - 36$  are -6 and 6 .
