What is the completely factored form of 25x4 – 16y2?

erastovalidia [21]

Answer:

$(5x^2+4y)(5x^2-4y)$

Step-by-step explanation:

$25x^4-16y^2$ has the form $a^2-b^2$ known as a difference of squares. It factors into (a+b)(a-b). To find a and b you take the square root.

$\sqrt{25x^4} =5x^2$

$\sqrt{16y^2} =4y$

The factored for is (a+b)(a-b).

In this case, it is $(5x^2+4y)(5x^2-4y)$

iren2701 [21]

Answer:

Step-by-step explanation:

We can use the geometric mean theorem:

The altitude on the hypotenuse is the geometric mean of the two segments it creates.

In your triangle, the altitude is the radius CM and the segments are AC and BC.

$CM = \sqrt{AC \times BC} = \sqrt{ 9 \times 4} = \sqrt{36} = \mathbf{6}\\\text{The radius of the circle M is $\large \boxed{\mathbf{6}}$}$
