Solve :-x4-6x2+8=0

Short Answer

Expert verified

Solution for equation will be

  • x=+2
  • x=-2
  • x=+2
  • x=-2

Step by step solution

01

Step 1.  Given Data

Quadratic Equation isx4-6x2+8=0

02

Step 2.  To Find

We have to solve it and find the value of x.

03

Step 3.  Explanation

Let the value of x2=u

Then the equation is -

(x2)2-6x2+8=0

Put the value of x2=u

u2-6u+8=0

(u-4)(u-2)=0

By using Zero product property -

u-4=0,u-2=0

u=4,u=2

04

Step 4.  Calculation

Replace u with x2

x2=4,x2=2

x=卤4,x=卤2

x=卤2,x=卤2

There are four solutions -

  • x=+2
  • x=-2
  • x=+2
  • x=-2
