What is the completely factored form of d4 -8d2 + 16

irinina [24]

According to Vieta's Formulas, if $x_1,x_2$ are solutions of a given quadratic equation:

$ax^2+bx+c=0$

Then:

$a(x-x_1)(x-x_2)$ is the completely factored form of $ax^2+bx+c$ .

If choose $x=d^2$ , then:

$\displaystyle x^2-8x+16=0\\\\x_{1,2}= \frac{8\pm \sqrt{64-64} }{2}=4$

So, according to Vieta's formula, we can get:

$x^2-8x+16=(x-4)(x-4)= (x-4)^2$

But $x=d^2$ :

$d^4-8d^2+16=(d^2-4)^2=[(d+2)(d-2)]^2=(d+2)^2(d-2)^2$

Answer,

5

Explanation,

Simply input the numbers in the equation & solve.

(12)(3) − 3(1/3)/(4)(3) − 5

= 36 − 3(1/3)/(4)(3) − 5

= 36 − 1/(4)(3) − 5

= 35/(4)(3) − 5

= 35/12 − 5

= 35/7

= 5

Hope This Helps :-)
