Question

find the zero of y2+3/2×√5y-5 by factorization method and verify the relation between between the zeros and coefficient of polynomial. please do it fast

Answer 1

given=
$y ^{2} + 3 \sqrt{5} y \div 2 - 5$
→ 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
$- 3 \sqrt{5} + 5 \sqrt{5} \div 4 \: or \: - 3 \sqrt{5} - 5 \sqrt{5} \div 4$
