Answer 1

Answer:

This will surely help you

Answer 2

==> x² - 3√5x + 10 = 0

On comparing this Quadratic equation with the standard form of Quadratic equation (i.e, ax² + bc + c = 0 ) , we get

a = 1, b = -3√5 , c = 10

Discriminant, D = b² - 4ac

==> D = (-3√5)² - 4*1*10

==> D = 45 - 40

==> D = 5

We know,

x = ( -b ± √D ) / 2a

x = ( -(-3√5) ± √5 ) / 2×1

x = ( 3√5 ± √5 ) / 2

Case-1:

==> x = (3√5 + √5) / 2

==> x = 4√5 / 2

==> x = 2√5

Case-2:

==> x = (3√5 - √5) / 2

==> x = 2√5 / 2

==> x = √5

Hence, Zeroes of the following quadratic equation are 2√5 and √5
