(ii) Vzx? +7x+5V2 = 0
(v) 100x2 – 20x+1=0
Solve the problems given in​

Answer 1

Answer:

Step-by-step explanation:

1 ) x² - 3x - 10 = 0

⇒ x² - 5x + 2x - 10 = 0

⇒ x ( x - 5 ) +2 ( x - 5 ) = 0

⇒ ( x + 2 ) ( x - 5 ) = 0

⇒ x = -2, 5

3 ) 100x² - 20x + 1 = 0

⇒ 100x² - 10x - 10x + 1 = 0

⇒ 10x ( 10x - 1 ) -1 ( 10x - 1 ) = 0

⇒ ( 10x - 1 ) ( 10x - 1 ) = 0

⇒ x = 1/10 , 1/10
