Question

Find the roots of the following by using formula x²-60x+800
(HINT:– -b±√b²-4ac/2a)​

Answer 1

Answer:

answer for the given problem is given

Answer 2

Answer:

Step-by-step explanation:

x²-60x + 800 = 0

we will use the given formula where a= 1, b=-60, c= 800

-(-60)±√(-60)²-4×1×800/2×1

60 ± √3600 - 3200/ 2

60 ±√400 / 2

60± 20 / 2

60 +20/2       or       60-20/2

80/2                or         40/2

40    or    20

answer can either be 40 or 20
