The following equation has three real solutions, one of which is zero:

22x^4 = 3x^2

Find the other (non-zero) solutions. List your answers separated by a comma. For example, if you found the solutions x=1 and x=2, you would enter 1,2.



Answer :

To solve the equation [tex]\( 22x^4 = 3x^2 \)[/tex], follow these steps:

1. Rewrite the equation:

Start by arranging the equation in standard polynomial form. Move all terms to one side of the equation:

[tex]\[ 22x^4 - 3x^2 = 0 \][/tex]

2. Factor the equation:

Factor out the common term [tex]\( x^2 \)[/tex]:

[tex]\[ x^2(22x^2 - 3) = 0 \][/tex]

3. Set each factor equal to zero and solve:

The equation [tex]\( x^2(22x^2 - 3) = 0 \)[/tex] implies two possible cases, based on the zero product property:

Case 1:
[tex]\[ x^2 = 0 \][/tex]
Solving for [tex]\( x \)[/tex], we get:
[tex]\[ x = 0 \][/tex]
This is one of the solutions.

Case 2:
[tex]\[ 22x^2 - 3 = 0 \][/tex]
Solving for [tex]\( x^2 \)[/tex] by isolating the term:
[tex]\[ 22x^2 = 3 \][/tex]
Divide by 22:
[tex]\[ x^2 = \frac{3}{22} \][/tex]
Taking the square root of both sides:
[tex]\[ x = \pm \sqrt{\frac{3}{22}} \][/tex]

4. Simplify the square root expression:

We can leave the solution in its exact form or approximate the square root numerically:
[tex]\[ x = \pm \sqrt{\frac{3}{22}} \approx \pm 0.369 \][/tex]

So, the other (non-zero) solutions to the equation are:
[tex]\[ x \approx -0.369, 0.369 \][/tex]

Hence, the non-zero solutions to the equation [tex]\( 22x^4 = 3x^2 \)[/tex] are:
[tex]\[ -0.369274472937998, 0.369274472937998 \][/tex]
