Recognize as difference of cubes: Recognize the expression as a difference of cubes.The given expression is 125v3−c3. We can see that 125 is a cube (53) and v3 and c3 are also cubes. So, the expression is a difference of cubes which can be factored using the formula a3−b3=(a−b)(a2+ab+b2).
Identify 'a' and 'b': Identify a and b in the formula for the difference of cubes.In the expression 125v3−c3, we can identify a as 5v (since 5v3=125v3) and b as c (since c3=c3).
Apply formula: Apply the difference of cubes formula.Using the formula from Step 1 and the values from Step 2, we get:125v3−c3=(5v)3−c3=(5v−c)((5v)2+(5v)(c)+c2).
Expand and simplify: Expand and simplify the terms in the factorization.Now we need to calculate (5v)2, (5v)(c), and c2:(5v)2=25v2,(5v)(c)=5vc,c2=c2.So the factorization becomes:(5v−c)(25v2+5vc+c2).
Write final form: Write down the final factorized form.The completely factorized form of the expression is:125v3−c3=(5v−c)(25v2+5vc+c2).
