Question

CAN SOMEONE JUST PLEASE ANSWER THIS ASAP FOR BRAINLIEST!!

Answer 1

3(6 + x) (6 - x)

I hope this helps. (:

Answer 2

Step  1  :

Equation at the end of step  1  :

 108 -  3x2

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  108 - 3x2  =   -3 • (x2 - 36)  

Trying to factor as a Difference of Squares :

3.2      Factoring:  x2 - 36  

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =  

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.  

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 36 is the square of 6

Check :  x2  is the square of  x1  

Factorization is :       (x + 6)  •  (x - 6)  

Final result :

 -3 • (x + 6) • (x - 6)
