Question
Factor Completelyk, to the power 4 , minus, 4, k, cubed, plus, 4, k, squaredk 4 −4k 3 +4k 2
Solution
The expression you provided is k^4 - 4k^3 + 4k^2. To factor this completely, follow these steps:
Step 1: Look for the greatest common factor (GCF). In this case, the GCF is k^2. So, factor out k^2 from each term:
k^2(k^2 - 4k + 4)
Step 2: Now, look at the expression inside the parentheses. It's a quadratic expression and can be factored further. It's in the form of a^2 - 2ab + b^2, which is a perfect square trinomial. It can be factored into (a - b)^2. Here, a is k and b is 2.
So, the factored form of the expression is:
k^2(k - 2)^2
This is the completely factored form of the given expression.
