Find the zeros of the function f ( x) = x 2 – 8 x – 9. Find x so that f ( x) = x 2 – 8 x – 9 = 0. f ( x) can be factored, so begin there. If a polynomial function with integer coefficients has real zeros, then they are either rational or irrational values.

The roots of any quadratic equation is given by: x = [-b +/- sqrt(-b^2 - 4ac)]/2a. Write down the quadratic in the form of ax^2 + bx + c = 0. If the equation is in the form y = ax^2 + bx +c, simply replace the y with 0. This is done because the roots of the equation are the values where the y axis is equal to 0.

If the discriminant is equal to zero, this means that the quadratic equation has two real, identical roots. Therefore, there are two real, identical roots to the quadratic equation x2 + 2x + 1. D > 0 means two real, distinct roots.

When there is no C value in the standard equation, it is understood to be C = 0 (has a Y intercept of 0), since . To solve quadratic equation (finding zeros aka X intercepts), first set the equation to zero () if not already set. Then you could factor if possible, or use the quadratic formula.

Solving a quadratic equation means we find two values ( from the equation) which. give the value of the quadratic equation as zero on substitution . The two values. are also called as zeros of the polynomials. For example can be written as (x + 2 ) ( x + 3 ) = 0.

a = 1, b = -8, c = 16. Apply the quadratic formula. Since the square root of 0 is 0, and adding or subtracting 0 both give the same result, there is only one possible value. This quadratic equation has only one solution, so the graph of the function will touch the x-axis once.

Roots are also called x-intercepts or zeros. A quadratic function is graphically represented by a parabola with vertex located at the origin, below the x-axis, or above the x-axis. Therefore, a quadratic function may have one, two, or zero roots. ... The roots of a function are the x-intercepts.

The correct answer is m = −8 or 3. You can find the solutions, or roots, of quadratic equations by setting one side equal to zero, factoring the polynomial, and then applying the Zero Product Property. The Principle of Zero Products states that if ab = 0, then either a = 0 or b = 0, or both a and b are 0.

An equation of the form ax2 + bx + c = 0 where a, b, and c are constants and a ≠ 0 is known as a quadratic equation. Here, it is equating to 0. Examples:x2 - 4x + 3 = 0, x2 - 3x = 0 etc. a polynomial when equated to zero or some value becomes an equation.

Roots are also called x-intercepts or zeros. A quadratic function is graphically represented by a parabola with vertex located at the origin, below the x-axis, or above the x-axis. Therefore, a quadratic function may have one, two, or zero roots. ... By definition, the y-coordinate of points lying on the x-axis is zero.
