Question

Find the zero and verify relation between zero and coefficient
25x(x+1)+4

Answer 1

Answer:

x = -1/5 and -4/5

Step-by-step explanation:

25x(x+1)+4

25x² + 25x + 4

25x² + 20x + 5x + 4

5x(5x + 4).+1(5x + 4)

(5x + 1)(5x + 4)

x = -1/5 and -4/5

verify their relation

sum of zeroes = -b/a

-1/5 + (-4/5) = -25/25

-5/5 = 1

-1 = -1

product of zeroes = c/a

-1/5 × (-4/5) = 4/25

4/25 = 4/25
