Answer
B. x=1/2
D. x=4/5
Explanation
[tex]20x^2-26x+8=0[/tex]
Divide by 2 both sides:
[tex]10x^2-13x+4=0[/tex]
Factoring:
[tex](2x-1)(5x-4)=0[/tex]
And we have 2 options:
[tex]\begin{gathered} 2x-1=0 \\ 2x=1 \\ x=\frac{1}{2} \end{gathered}[/tex]
and
[tex]\begin{gathered} 5x-4=0 \\ 5x=4 \\ x=\frac{4}{5} \end{gathered}[/tex]
