1.

Find the zeroes of the following polynomial:5v5x+30x+8V5

Answer»

5root(5)x^2 + 30x + 8root(5) = 0

5root(5)x^2 + 20x + 10x + 8root(5) = 0

5x(root(5)x + 4) + 2root(5)(root(5)x + 4) = 0

(5x + 2root(5)) + (root(5)x + 4)= 0

x = - 2/root(5), - 4/root(5)

Zeroes of given polynomial are - 2/root(5), - 4/root(5)
