5x + 10x + 16 = 0How many distinct real solutions does the given equation have?

Explanation

Choice D is correct. The number of solutions of a quadratic equation of the for max 2 +bx + =c 0, where a, b, and c are constants, can be determined by the value of the discriminant, b2 -4ac If the value of the discriminant is positive, then the quadratic equation has exactly two distinct real solutions. If the value of the discriminant is equal to zero, then the quadratic equation has exactly one real solution. If the value of the discriminant is negative, then the quadratic equation
