WebExample Problem 1: Finding the Zeros of a Quadratic Function Find the zeros of the quadratic function f(x) = 2x2+9x+9 f ( x) = 2 x 2 + 9 x + 9 by finding the values of x that … WebZZeros of Quadratic Functionseros of Quadratic Functions A zero of a functionf is an x-value for which f(x) = 0. If a real number kis a zero of the function f(x) =ax2+bx+c, then kis an x-intercept of the graph of the function. Example 1 Find the zeros of each function. a. f(x) = 9x2− 1 b. f(x) =x2− 2x− 8 Set f(x) equal to 0. WebSolution: To find the zeros of the function f (x) = x 2 + 6x + 9, we will first find its factors using the algebraic identity (a + b) 2 = a 2 + 2ab + b 2. We have f (x) = x 2 + 6x + 9 = x 2 + 2 × x × 3 + 3 2 = (x + 3) 2 Now, f (x) = 0 ⇒ (x + 3) 2 = 0 ⇒ (x + 3) = 0 and (x + 3) = 0 ⇒ x = -3, -3 Answer: The zeros of f (x) = x 2 + 6x + 9 are -3 and -3. legacy saviour schembri
