Solve x4 – 17x2 + 16 = 0.<br> Let u =<br> Select all of the zeroes of the function. i i

Soloha48 [4]

$Solve \ x^4 - 17x^2 + 16 = 0$

To solve this equation , we need to write it in quadratic form

$ax^2+bx+c=0$

To get the equation in quadratic form we replace x^2 with u

$x^2 = u$

$x^4 - 17x^2 + 16 = 0$ can be written as

$(x^2)^2 - 17x^2 + 16 = 0$ , Replace u for x^2

So equation becomes

$u^2 - 17u + 16 = 0$

Now we factor the left hand side

-16 and -1 are the two factors whose product is +16 and sum is -17

(u-16) (u-1) = 0

u -16 = 0 so u=16

u-1 =0 so u=1

WE assume u = x^2, Now we replace u with x^2

$u = 16 so \ it \ becomes \ x^2 =16$

Now take square root on both sides , x= +4 and x=-4

$u = 1 so \ it \ becomes \ x^2 =1$

Now take square root on both sides , x= +1 and x=-1

So zeros of the function are -4, -1, 1, 4

ANEK [815]

Answer:

$d = -\dfrac{1}{4}$

Step-by-step explanation:

Given

$6d-\dfrac{11}2=2d-\dfrac{13}{2}$

Required

Solve for d

$6d-\dfrac{11}2=2d-\dfrac{13}{2}$

Collect Like Terms

$-2d + 6d=-\dfrac{13}{2}+\dfrac{11}{2}$

$4d=-\dfrac{13}{2}+\dfrac{11}{2}$

Take LCM

$4d=\dfrac{-13+11}{2}$

$4d=\dfrac{-2}{2}$

$4d = -1$

Make d the subject

$d = -\dfrac{1}{4}$
