    Answer:

    you can express the given equation as :

    2(x²+1)=5x

    => (x-2)(2x-1)=0 , then solve for x , you can do it yourself ,it’s not very difficult.

    Step-by-step explanation:

    2(x²+1)=5x

    or, 2x²-5x+2=0

    or, 2x²-4x-x+2=0

    or, 2x(x-2)-1(x-2)=0

    or, (x-2)(2x-1)=0

    please try next steps yourself hope it helps , you can do it.
