How do you find the roots of Y?

Since the roots of a function are the points at which y = 0, we can find the roots of y = ax2 + bx + c = 0 by factoring ax2 + bx + c = 0 and solving for x. We can also find the roots of y = ax2 + bx + c = 0 using the quadratic formula, and we can find the number of roots using the discriminant.

How many roots does the equation x2 2x 1 0?

two roots
Alternatively, you could say that x2−2x+1=0 has exactly two roots, counting multiplicity.

What is an equal root?

In a quadratic equation ax^2 + bx+ c = 0 the two roots are equal if the value of the discriminant. b^2–4. a.c is equal to zero. If it is positive then we have two real (but unequal) roots, if it is negative then we have two complex (conjugate) roots.

What is the root of polynomial equation 2x 3 0?

So, the correct answer of this question is option (3) -3/2.

How do you find the roots of a graph?

When that function is plotted on a graph, the roots are points where the function crosses the x-axis. For a function, f (x) f (x), the roots are the values of x for which f (x) =0 f (x) = 0. For example, with the function f (x) =2 −x f (x) = 2 − x, the only root would be x = 2 x = 2, because that value produces f (x) = 0 f (x) = 0.

How do you find the roots of a simple problem?

Of course, it’s easy to find the roots of a trivial problem like that one, but what about something crazy like this: Set each factor in the numerator to equal zero. Solve that factor for x. Check the denominator factors to make sure you aren’t dividing by zero!

How do you find the root of a function?

Roots of a function are x-values for which the function equals zero. They are also known as zeros. When given a rational function, make the numerator zero by zeroing out the factors individually. Check that your zeros don’t also make the denominator zero, because then you don’t have a root but a vertical asymptote.
