Question

find the zeros of the given polynomials by factorization method and verify the relationship between the zeros and the coefficients of the polynomial : y^2 + 3/2√5 - 5​

Answer 1

Answer:

given=

y ^{2} + 3 \sqrt{5} y \div 2 - 5y

2

+3

5

y÷2−5

→ however the given px cannot be factorised,

but we can find the zeroes by completing the square method or by quadratic formula

→ i will be using completing the square method.

→ zeroes are

- 3 \sqrt{5} + 5 \sqrt{5} \div 4 \: or \: - 3 \sqrt{5} - 5 \sqrt{5} \div 4−3
