Question

Find the zeroes of the quadratic polynomials i) x2 + 5x + 6 ii) x2 –(√3 + 1)x + √3 and

verify the relationship between the zeroes and their coefficients.​

Answer 1

Answer:

2√3x2 ˗ 5x + √3 ⇒ 2√3x2 ˗ 2x ˗ 3x+ √3 ⇒ 2x (√3x ˗ 1) ˗ √3 (√3x ˗ 1) = 0 ⇒ (√3x ˗ 1) or (2x − √3) = 0 ⇒ (√3x ˗ 1) = 0 or (2x − √3) = 0 ⇒ x = 1/ √3 or x = √3/ 2 ⇒ x = 1/ √3 × √3 /√3 = √3/ 3 or x = √3/ 2 Read more on Sarthaks.com - https://www.sarthaks.com/128309/find-the-zeroes-the-polynomial-23x-and-verify-the-relation-between-zeroes-coefficients
