Answer:

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'
