Answer 1

Answer: b&d

Explanation:

Answer 2

B and D

Explanation:

The quadratic formula is
`x=(-b+/-√(b^2-4ac) )/(2a)`. Here a=20, b=-26, and c=8.

Substitute and you'll have:

`x=(-b+/-√(b^2-4ac) )/(2a) =(26+/-√(26^2-4(20)(8)) )/(2(20))=(26+/-√(676-640) )/(40))`

`(26+/-√(36) )/(40)=(26+/-6 )/(40)`

This means the solutions are 26 - 6/ 40 and 26 + 6/ 40.

It simplifies to 1/2 and 4/5.
