Question

5x² - 6x-2=0use completing square method

​

Answer 1

Answer:

Discriminant = b2 – 4ac

= 36 – 4 × 5 × (–2)

= 76 > 0

So, the given equation has two distinct real roots.

5x2 – 6x – 2 = 0

Multiplying both sides by 5.

(5x)2 – 2 × (5x) × 3 = 10

(5x)2 – 2 × (5x) × 3 + 32 = 10 + 32

(5x – 3)2 = 19

5x – 3 = ±√19

x = (3 ± √19)/5

Step-by-step explanation:

hope it helps u✌✌

Answer 2

Step-by-step explanation:

• (5x^2)/5- 6x/5- 2 /5 =0/5
• x^2-6x/5 = 2/5
• x^2 - 2. x3/5 + (3/5)^2 =2/5 + (3/5)^2
• (x-3/2)^2 = (10+ 9)/25
