ANSWER

True

Step-by-step explanation

The given quadratic polynomial is


32 {x}^(2) + 16x - 57

We have a=32,b=16,c=-57

Recall and use the discriminant,


D = {b}^(2) - 4ac


D = {16}^(2) - 4(32)( - 57)


D =256 + 7296 = 7552

Since the discriminant is positive, the polynomial has two real roots.

The correct choice is True
