Q:
# If 2x2 – 13x + 20 = (2x – 5)(x – 4), which equation(s) should be solved to find the roots of 2x2 – 13x + 20 = 0? Check all that apply. A. 2x – 5 = 0 B. x + 4 = 0 C. 2x – 5 = x – 4 D. 2x + 5 = 0 E. x – 4 = 0

Accepted Solution

A:

2x^2 – 13x + 20

= (2x – 5)(x – 4)

to find roots of 0 then (2x – 5)(x – 4) = 0

then (2x – 5) = 0 and (x – 4) = 0

answer

A. 2x – 5 = 0

E. x – 4 = 0

= (2x – 5)(x – 4)

to find roots of 0 then (2x – 5)(x – 4) = 0

then (2x – 5) = 0 and (x – 4) = 0

answer

A. 2x – 5 = 0

E. x – 4 = 0
