the zeroes and the coefficients.
(1) x² – 2x - 8
(ii) 452 - 4s +1 ©
(in) 6x2 - 3 - 7x
(iv) 4u²+ 8u (60 - 150
( 3x² - x - 40​

Answer 1

Answer:

Example 4: If α and β are the zeros of ax2 + bx + c, a ≠ 0 then verify the relation between the zeros and its coefficients. Sol. Since a and b are the zeros of polynomial ax2 + bx + c. Therefore, (x – α), (x – β) are the factors of the polynomial ax2 + bx + c.
