Question

. Use the discriminant to determine the number of real roots for the quadratic equation. y = x^2 – 10x + 25

Answer 1

a) one real root
b) two real roots
c) no real roots
d) no solution to the equation

Answer 2

\[D = \sqrt{b^2 - 4ac}\]

That is the discriminant for ax^2 + bx + c

Answer 3

can you find a, b, and c for your problem?

Answer 4

I refuse... completing the square is so much better in this case !

Answer 5

this doesnt help -.-

Answer 6

a is the coefficient of x^2 term
b is the coefficient of x term
c is the constant

Answer 7
