Question

The roots of the quadratic equation are xsquare-9x+20 is equal to zero​

Answer 1

Step-by-step explanation:

x² - 9x + 20 = 0

x² - 5x - 4x + 20 = 0

x (x-5) -4 (x-5) = 0

x=5,4

zeroes are 5 and 4

Answer 2

Answer:

x²-9x+20

= x²-4x-5x+20

= x(x-4)-5(x-4)

= (x-4)(x-5)

ROOTS,

x-4 = 0

x = 4

x-5 = 0

x = 5

Zeroes of the quadratic equation is 4 and 5.
