    Answer:

    The values of a and b from the quadratic equation 2×2 – 5x + 7 = 0 are – 0.1419 and + 2.6419.  These answers are explained step -wise  below :

    – A quadratic equation is defined as an equation which on standard form can be rearranged as ax2 + bx + c = 0;

    where x represent unknown number and a, b , c are the known numbers where a is not equal to zero but if its equals to zero then equation becomes linear.

    – The given quadratic equation is:

    2x²+5x-7 = 0

    so, here the values of a, b and c are

    a= 2 ;

    b= -5 ;

    and c= 7

    Putting these values in the formula of the quadratic equation given in the picture given below.
