What are the zeros of the quadratic function f(x)=8x^2-16x-15
____ [38]

Step-by-step explanation:

<u>Step 1:  Use the quadratic formula to find the zeros</u>

<u />x=\frac{-b\pm \sqrt{b^2-4ac} }{2a}

x=\frac{-(-16)\pm \sqrt{(-16)^2-4(8)(-15)} }{2(8)}

x=\frac{16\pm \sqrt{736} }{16}

x=\frac{16\pm 4\sqrt{46} }{16}

x=\frac{4\pm \sqrt{46} }{4}

Answer:  x=\frac{4\pm \sqrt{46} }{4}
