WebQuestion. Find all the zeros of the polynomial function. g (x)=x^ {4}-9 x^ {3}+23 x^ {2}-81 x+126 g(x) = x4 −9x3 + 23x2 −81x +126. Web23 feb. 2024 · We put g (x) = 0 ⇒ a (x2+1)–x (a2+1) = 0 ⇒ ax2 + a − a2x – x = 0 ⇒ ax2 − a2x – x + a = 0 ⇒ ax (x − a) − 1 (x – a) = 0 ⇒ (x – a) (ax – 1) = 0 This gives us 2 zeros, for x = a and x = 1/a Hence, the zeros of the quadratic equation are a and 1/a. Now, for verification Sum of zeros = – coefficient of x / coefficient of x2 a + 1/a = – (- (a2 + 1)) / a

WebSo, the formula that we use to find the zeros of a quadratic polynomial ax 2 + bx + c = 0 is: x = [- b ± √ (b 2 - 2ac) ] / 2a Sum and Product of Zeros of Polynomial The zeros of a polynomial can be easily calculated with the help of: Sum and Product of Zeros of Polynomial for Quadratic Equation WebThe graph touches the x x -axis at (-2,0) (−2,0) , since -2 −2 is a zero of even multiplicity. The graph crosses the x x -axis at \left (\dfrac23,0\right) (32 ,0) , since \dfrac23 32 is a zero of odd multiplicity. Finally, let's finish this process by plotting the y y -intercept (0,-8) (0,−8) and filling in the gaps with a smooth, continuous curve. WebThus, the zeros of the function are at the point . Our online calculator, based on Wolfram Alpha system is able to find zeros of almost any, even very complicated function. … sohl memory foam rollaway bed
