Answer:

x = {-0.454, 15.954}

Step-by-step explanation:

we can solve this equation by putting it into the quadratic formula

x = [-b +/- sqrt(b^2 - 4ac)] / 2a

x = [-248 +/- sqrt(248^2 - 4(-16)(116))] / 2(-16)

x = [-248 +/- sqrt(61504 + 7424)] / -32

x = [-248 +/- sqrt(68928)] / -32

x = (-248 +/- 262.541425) / -32

x = (-248 + 262.541425) / -32

x = (-248 - 262.541425) / -32

x = {-0.454419531, 15.9544195}

rounding to the nearest thousandth would make it x = {-0.454, 15.954}
