Question

Add x²-a², -5x²+2a², -4x²+4a²
Please answer

Answer 1

Answer:

(x²-a²)+(-5x²+2a²)+(-4x²+4a²)

Let's simplify step-by-step.

x²−a²−5x²+2a²−4x²+4a²

=x²+−a²+−5x²+2a²+−4x²+4a²

Combine Like Terms:

=x²+−a²+−5x²+2a²+−4x²+4a²

=(−a²+2a³+4a²)+(x²+−5x²+−4x²)

=5a²−8x²

Answer 2

Answer:

a(x²+1)= (a²+1)x

ax² + a= (a²+1)x

ax²-(a²+1)x+a=0

Using the quadratic formula

X= -b±√b²-4ac/2a

X= -(-a²-1)±√[-(a²+1)]²-4.a.a /2a

X= a²+1±√a ^4+1+2a²-4a² /2a

X= a²+1±√a^4+1-2a² /2a

X = a²+1±√(a²-1)² /2a

X= a²+1± a²-1 /2a

∴x= a²+1+a²-1 /2a & x= a²+1-a²+1 /2a

x =a, & x= 1/a
