Answer 1

Hi there!

Here,

→ a = 5
→ b = -29
→ c = 5

5x² - 29x + 20 = 0

5x² - 25x - 4x + 20 = 0

5x (x - 5) - 4 (x - 5) = 0

(x - 5) (5x - 4) = 0

x = 5 Or x = 4 / 5

∴ a = 5 n' b = 4 / 5

Now,

¡¡ Sum of zeroes ¡¡

→ a + b = 5 + 4 / 5

= 4 + 25 / 5

= 29 / 5

→ a + b = -b / a

= -(-29) / 5

= 29 / 5

∴ a + b = -b / a = 29 / 5. ---[ verified. ]

¡¡ Product of zeroes ¡¡

→ a × b = 5 × 4 / 5

= 20 / 5

= 4

→ a × b = c / a

= 20 / 5

= 4

∴ a × b = c / a. ---[ verified. ]

Hope it helps! :)
