Question

25y^2-y^4=? срочно надо

Answer 1

У^2(25-у^2)
у^2(5-у)(5+у)

Answer 2

To solve the expression, you need to factor it first. The given expression is:

25y^2 - y^4

Now, let's factor it:

y^2(25 - y^2)

Next, we can factor further using the difference of squares formula (a^2 - b^2 = (a + b)(a - b)):

y^2(5^2 - y^2)

Now we have:

y^2(5 + y)(5 - y)

So, the fully factored expression is:

y^2(5 + y)(5 - y)

If you need to simplify further, you can multiply out the y^2 with the other two terms:

y^2(5 + y)(5 - y) = y^2(25 - y^2) = 25y^2 - y^4

So, the final answer is 25y^2 - y^4.
