Answer 1

where is the question ???????????

Answer 2

Answer:

$A=\frac{-3-\sqrt{21}}{2}\text{ and B = }\frac{-3+\sqrt{21}}{2}$

Step-by-step explanation:

The function is given to be f(x) = 2x² + 6x - 6

We need to find the zeros of the given function f(x)

Now, to find the zeros of the given function f(x) we find the values of x such that f(x) = 0

⇒ f(x) = 0

⇒ 2x² + 6x - 6 = 0

⇒ x² + 3x - 3 = 0

$\implies x=\frac{-3\pm \sqrt{9+4\times 3}}{2}\\\\\implies x=\frac{-3\pm\sqrt{21}}{2}$

$Hence,\:\: A=\frac{-3-\sqrt{21}}{2}\text{ and B = }\frac{-3+\sqrt{21}}{2}$
