Question

What are the values of a, b, c for the equation 2 x to the power of 2 end exponent plus 5 x minus 8 equals 0.

  1. 2, -5, -8    
  2. 2, 5, -8    
  3. 2, 5, 8    
  4. -2, 5, -8    

Hint:

Any equation of the form p (x) = 0, where p (x) is a polynomial of degree 2, is a quadratic equation

The correct answer is: 2, 5, -8


    Step 1 of 1:
    We have given a quadratic equation 2 x to the power of 2 end exponent plus 5 x minus 8 equals 0.
    Now,
    2 x to the power of 2 end exponent plus 5 x minus 8 equals 0
    a = 2, b = 5, c = - 8

    In a general quadratic equation is a x squared plus b x plus c equals 0.
