Use the discriminant to describe the roots of each equation. Then select the best description. 2x2 + 7x + 6 = 0 double root real and rational roots real and irrational roots non-real roots

So the equation to find the discriminant is √(b^2 - 4ac), with a = x^2 coefficient, b = x coefficient, and c = constant. Using our equation above, we can solve for it as such:


√(7^2-4*2*6)\\ √(49-48)\\ √(1)\\ 1

Since the discriminant is greater than zero and a perfect square, this means that there are 2 real, rational solutions to this polynomial.
