What are the solutions of the equation x4 + 95x2 – 500 = 0? use factoring to solve.

Step-by-step explanation:

REwrite the equation in the form of quadratic equation ax^2+bx+c=0

To solve for x , we replace x^2 by 'u'

Now we factor the left hand side

Product is -500 and sum is 95

100 times -5 is -500

100 + (-5) is 95, factors are 100 and -5

Replace u with x^2

Set each factor =0 and solve for x

To remove square , take square root on both sides

square root (-1) is 'i'
