Question 223983
{{{f(x)= -2x^2-6x+5}}}


Step 1.  To find the x-intercepts,set the equation equal to zero (that is f(x)=y=0}}}


{{{-2x^2-6x+5=0}}}



Step 2.  To solve, you can use the quadratic formula given as


{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a)}}}


where a=-2, b=-6 and c=5.


*[invoke quadratic "x", -2, -6, 5 ]


I hope the above steps and explanation were helpful.
