ANSWER

The given trinomial will have two distinct real solutionss.

EXPLANATION

The given trinomial is


5 {x}^(2) - 2x - 3

When we compare to


a{x}^(2) + bx + c

, we have a=5, b=-2, c=-3

The discriminant of a quadratic trinomial helps us to predict the nature of the roots of a quadratic trinomial without necessarily solving for them.

We now use the discriminant

D=b²-4ac

to obtain,


D= {( - 2)}^(2) - 4(5)( - 3)


D=4 + 60 = 64

Since the discriminant is positive, the trinomial will have two distinct real solutions.

Answer: Two distinct real roots.

Explanation:

Given a quadratic equation
ax^2+bx+c=0, we can predict the type of solution by calculating the Discriminant (D):


D=b^2-4ac

Identify a, b and c from
5x^2- 2x-3=0.


a=5\\b=-2\\c=-3

Substitute into the formula of the Discriminant. Then:


D=(-2)^2-4(5)(-3)\\D=64

The discriminant obtained is greater than zero.

When
D>0 the type of solution is: two distinct real roots.
