Y = 16x^2+ 40x + 25 

<span>The sign before the 16 is positive, so it's a parabola with a minimum. The x coordinate of the minimum is: </span>
<span>x=-b/2a=-40/32=5/4=-1.25 </span>

<span>If you fill that in, you get y=0 </span>

<span>so the coordinates are (1.25, 0)</span>

Kindly proofread the question!!!

The leading term is x^6, not x5.


Answer: The additional roots are -2, +2, each with multiplicity 2.


Step-by-step explanation:

x^6 - 16x^2 = 4x^4 - 64


x^6 - 4x^4 - 16x^2 + 64 = 0

(x+2i)(x-2i) = (x^2+4) is a factor.

(x-2)(x+2)(x-2)(x+2)(x^2+4) = 0

Polynomial long division by x^2+4

x^6 - 4x^4 - 16x^2 + 64 = 0

First term of quotient is x^4

Subtract x^6+4x^4

Remainder is -8x^4 -16x^2+64

Second quotient term is -8x^2

Subtract -8x^4-32x^2

Remainder is 16x^2+64

Third quotient term is 16

Subtract 16x^2+64

Remainder is zero

Quotient is x^4 - 8x^2 + 16

(x^2-4)^2 = x^4 + 2(1)(-4)x^2 + 16

(x-2)(x+2)(x-2)(x+2)(x^2+4) = 0
