Answer 2

Step-by-step explanation:

step 1: x²-6/5 x -2/5 = 0 divding equation with 5

step 2 : x²-6x/5 = 2/5

step 3: x²-6x/5 + (3/5)² = 2/5 +(3/5)² adding (3/5)² on both sides

step 4: (x- 3/5)² = 2/5 + 9/25

step 5: (x- 3/5)² = 19/25

step 6: x-3/5=√19/√25

step 7: x = 3/5+√19/5

so x = 3+√19/5

s0 x = 3+√19/5 or 3-√19/5

this is the completing square method
