Question

If a quadratic equation, like x^2-2x+1 = 0 has two identical roots, does it mean that there is only one root or two?

Answer 1

Only one - the vertex of the parabola intersects with the x axis

Answer 2

This is called a bounce in higher-order functions

Answer 3

yes they would both be equal so there would be one root. you can find out how many roots a quadratic equation will have using the discriminative formula b^2 -4ac
if the answer is bigger than 0 it has 2 roots if the answer is 0 then it has one if the answer is less than 0 it has no real roots

Answer 4

there's only one.:)
