Question

Find the roots of the eqution 5x²- 6x -2 = 0 by the method of completing the square method ​

Answer 1

Step-by-step explanation:

5x^2-6x-2

1. divide equation by 5
2. we get x^2-6/5x-2/5=0
3. a=5 b=6/5 c= 2/5

so (1/2×6/5)^2

=9/25

x^-6/5x+9/5-9/5-2/5=0

x^2-6/5+9/5=9/5+2/5

x^2-6/5+9/5=7/5

(x+√9/5)=√7/5

x=-√9/5+√7/5 or. x= -√9/5-√7/5
