$3a-4a+9=-12a+43-6a$
$-a+9=-12a+43-6a$
$-a+9=-18a+43$
$-a+9+18a=43$
$17a+9=43$
$17a=43-9$
$17a=34$
$a=34:17$
$a=2$

The answer is: a=2

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