    Answer:

    136

    Step-by-step explanation:

    as you know that discriminant of a quadratic equation is

    D= b² – 4ac

    here, according to the give equation

    x² + 10x -7 -2= 0

    x²+ 10x -9 = 0

    b= 10 , c= -9 and a= 1

    by putting all these values in D.

    you can get the value of discriminant which is 136.

    I got this explained answer from an app called GAUTHMATH. Which is completely dedicated to maths problem. You can check it out too. It’s available on Play Store and App Store.

    hope this helps.
