Question

solve the equation : 5x -- 6x +1 by using formula

Answer 1

5x2 -5x-1x+1
5x (x-1)-1 (x-1)
(5x-1)(x-1)

Answer 2

Answer:

x = 1, 1/5

Step-by-step explanation:

Small correction in Question:

Question = 5x² - 6x + 1

• a = 5
• b = -6
• c = 1

Step 1: Calculating Discriminant:

⇒ D = b² - 4ac

⇒ D = ( -6 )² - 4 ( 5 ) ( 1 )

⇒ D = 36 - 20 = 16

Step 2: Substituting in the formula:

Formula:

• x = -b ± √D / 2a   [ Here, D = b² - 4ac ]

⇒ x = - ( -6 ) ± √16 / 2 ( 5 )

⇒ x = 6 ± 4 / 10

⇒ x = 1,  1/5

Hence the values or solutions of this equation are: 1 and 1/5

Hope it helped !!
