The roots of the polynomial for this case will be x1 = 6, x2 = -6, x3 = 4, x4 = -4.You can solve the polynomial using the resolver after making the variable change u = x ^ 2 so that you have a second degree polynomial. Then return the change to find the missing roots. Attached solution.

Answer:

x=-6,-4,4,6.

Step-by-step explanation:

We have been given an equation x^4-52x^2+576=0. We are asked to find the real or imaginary solutions of the given equation.

First of all, we will substitute u=x^2 in our given equation as:

(x^2)^2-52x^2+576=0

(u)^2-52u+576=0    

Now, we  will solve for u as:

u^2-36-16u+576=0

u(u-36)-16(u-36)=0

(u-36)(u-16)=0

u-36=0\text{ (or) }u-16=0

u=36\text{ (or) }u=16  

Now, we will undo substitution as:

x^2=36\text{ (or) }x^2=16

x=\pm\sqrt{36}\text{ (or) }x=\pm\sqrt{16}

x=\pm6\text{ (or) }x=\pm\sqrt4

Therefore, the solutions of our given equation are x=-6,-4,4,6.

Verify the identity. <br><br> sin (x+pi/2)=cos x
hram777 [196]
Given data 
<span>sin (x+pi/2)=cos x
</span>now using sin law
sin(a+b)=sin(a)cos(b)+cos(a)sin(b)
now using above values
sin(pi/2+x)=sin(pi/2)cos(x)+cos(pi/2)sin(x)
as we know that
sin(pi/2)=1
cos(pi/2)=0
now putting these values
sin(pi/2+x)=1*cosx+0*1
sin(pi/2+x)=cosx
hence proved that

<span>sin (x+pi/2)=cos x</span>
