WebJun 12, 2024 · For zeros, we first need to find the factors of the function x^ {2}+x-6 x2 + x − 6. The factors of x^ {2}+x-6 x2 + x − 6 are (x+3) and (x-2). Now we equate these factors with zero and find x. i.e., x+3=0 x + 3 = 0 and x-2=0 x − 2 = 0. i.e., x=-3 x = −3 and x=2 x = 2. In a simple way, x^ {2}+x-6=0 x2 + x − 6 = 0.

WebThe Factor Theorem is another theorem that helps us analyze polynomial equations. It tells us how the zeros of a polynomial are related to the factors. Recall that the Division Algorithm. If k is a zero, then the remainder r is f(k) = 0 … WebWe can determine if the zeros of a quadratic function are real, complex, or repeated using the discriminant formula. So, for a function f (x), its zeros are values of x when f (x) = 0. Hence, if we have f (a) = 0, then 'a' is a zero of the function f (x). Web2x+1 is a linear polynomial: The graph of y = 2x+1 is a straight line. It is linear so there is one root. Use Algebra to solve: A "root" is when y is zero: 2x+1 = 0. Subtract 1 from both sides: 2x = −1. Divide both sides by 2: x = −1/2. And that is the solution: x … grassy ridge bald roan mountain
