Find real or imaginary solutions of x^4-10x^2=-9

Mathematics
1 answer:
malfutka [58]3 years ago
6 0
This resembles a quadratic and we can factor it using that pattern.

(x^2)^2-(10x^2)+9=0

(x^2-9)(x^2-1)

(x+3)(x-3)(x+1)(x-1)=0

Sedaia [141]

Answer: 4(7-u)

Step-by-step explanation:

In order to factor, you have to find the GCF (Greatest Common Factor)

28:1, 28, 2, 14, 4, 7

artcher [175]

Answer:

AC = 10

Do you really need the explanation it seems like you are taking a test. I answered one of your questions a few seconds ago.

a^2+b^2=c^2.

8^2 + 6^2 = c^2

64 + 36 = c^2.

100 = c^2.

Square root of it all equals to

c = 10.
