Answer:
3(x-7)(x+7)
Step-by-step explanation:
In order to completely factor, begin by factoring out the greatest common factor. Both terms are divisible by 3 so 3 is the greatest common factor. 3(x^2-49). In order to completely factor, recognize x^2-49 as the difference of squares. Factor that into 3(x+7)(x-7).
Answer:
3(x+7)(x-7)
Step-by-step explanation:
Hello!
We can start by taking out the coefficient of 3 by factoring it out.
Factor:
The process of removing a factor or coefficient by dividing it out from the expression.
Factor the expression:
Remove the coefficient of 3
Factor using the product rule: a² - b² = (a+b)(a-b)
There's your factored expression! 3(x+7)(x-7)
