Question

(3 x 7=21)
27. Find the zeroes of the following polynomiai: 5V5X? + 30% + 815​

Answer 1

Step-by-step explanation:

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)
