Question

How many solutions are there for the equation x to the power of 2 end exponent plus 4 x plus 3 equals 0 using the discriminant?

  1. 0    
  2. 1    
  3. 2    
  4. Either 1 or 2.    

hintHint:

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


    Step 1 of 1:
    We have given a quadratic equation x to the power of 2 end exponent plus 4 x plus 3 equals 0
    Now,
    b to the power of 2 end exponent minus 4 a c equals 4 to the power of 2 end exponent minus 4 blank cross times blank 1 blank cross times blank 3
    equals 4 greater than 0
    The discriminant value is greater than zero, so it has two real solution.

    The discriminant is the part of the quadratic formula found within the square root.
