What is the factor of X cube 125?
Rewrite 125 as 53 . Since both terms are perfect cubes, factor using the difference of cubes formula, a3−b3=(a−b)(a2+ab+b2) a 3 – b 3 = ( a – b ) ( a 2 + a b + b 2 ) where a=x and b=5 .
What is the solution to the equation x3 125?
Answer and Explanation: The solution to the equation x3 – 125 = 0 is x = 5. Our equation is a cubic equation that contains just one variable term.
How do you factor 125?
1× 125 = 125 and 5 × 25 = 125; thus, the factors of 125 are 1, 5, 25, and 125.
What is the factored form of x3 125 Brainly?
Answer: Factor x3 – 125 as (a – b)(a2 + ab + b2), substituting a = x and b = 5 into the expression. Square the first and last terms, and rewrite (x)(5) as 5x.
