Y=13 square root 2 or 18.4
Since the insides of a triangle add up to 180, and we know that one angle equates to 90, and the other two are 45, then both legs are congruent, and that the hypotenuse is leg radical (square root) 2

What is the completely factored form of d4 - 8d2 + 16?. A) (d2 + 4)(d2 - 4). B) (d2 - 4)(d2 - 4). C) (d2 + 4)(d + 2)(d - 2). D)

Wittaler [7]

For a quadratic equation, the negative of the numerical coefficient of the second term is the sum of the roots and the constant is their product. Let a and b be the roots such that,
a + b = 8
ab = 16
The values of a and b are 4 and 4. Such that the factors are,
(d² - 4)(d² -4)
Both the factors are difference of two squares. The final answer for this item is,
(d + 2)(d - 2)(d + 2)(d - 2)

This is letter D.
