How do you find the discriminant, describe the number and type of root, and find the exact solution using the quadratic formula given #x^2-16x+4=0#?
Equation has two real roots
Two roots are
Given quadratic equation is
Formula to find the roots
Where a, b, c are the coefficients of
If the discriminant term is
a) Positive - both the roots are real
b) Zero - one real solution
c) Negative - two complex solutions
Hence the equation has two real roots.
