What are the solutions of the equation x^4-9x^2+8=0? Use u substitution to solve.
vodka [1.7K]

Answer:

The answer is the second option

Step-by-step explanation:

Let u=x^2.

( {x}^{2} ) {}^{2}  - 9( {x}^{2} ) + 8( {x}^{2} ) {}^{0}

{u}^{2}  - 9u + 8

(u - 1)(u - 8)

u = 1

u = 8

Set this equal to x^2

{x}^{2}  = 1

x = 1

or

x =  - 1

{x}^{2}  = 8

x = 2 \sqrt{2}

or

x =  - 2 \sqrt{2}

How to do question 4?
Nutka1998 [239]
Marie states that any integer greater than 4 will always get an even number of factors.

This can be proven wrong by (for example) 12.

12 has these factors:

1 x 12
2 x 6
3 x 4

12 has an ODD number of factor pairs.

Another example is 28.

28:
1 x 28
2 x 14
4 x 7

28 has an odd number of factor pairs.

I hope this helps!
