Answer:

x1=\frac{-2-2\sqrt{29401} }{245}  x2=\frac{-2+2\sqrt{29401} }{245}

Step-by-step explanation:

Step One: Convert

49/16x^2-2=-0.05x+4

Step Two: Multiply Both Sides by 80

245x^2-160=-4x+320

Step Three: Move everything to the left

245x^2+4x-480=0

Final Step: Quadratic Formula

x1=\frac{-2-2\sqrt{29401} }{245}  x2=\frac{-2+2\sqrt{29401} }{245}
