Final answer:
To factor the expression 30x-70x^4 completely, we can factor out a common factor of 10x. The factored form is 10x(3-7x^3).
Explanation:
To factor the expression 30x-70x4 completely, we need to look for a common factor in both terms. In this case, the common factor is 10x. We can factor out 10x from both terms to get: 10x(3-7x3)
In the second term, we can further factor by noticing that we have a difference of cubes. So, using the formula for factoring a difference of cubes, we can write: 10x(3-7x3) = 10x(3-^3) x (3^2+3+7x). This is the completely factored form of the expression.
