Answer:
![x1=\frac{-2-2\sqrt{29401} }{245} x2=\frac{-2+2\sqrt{29401} }{245}](https://tex.z-dn.net/?f=x1%3D%5Cfrac%7B-2-2%5Csqrt%7B29401%7D%20%7D%7B245%7D%20%20x2%3D%5Cfrac%7B-2%2B2%5Csqrt%7B29401%7D%20%7D%7B245%7D)
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}](https://tex.z-dn.net/?f=x1%3D%5Cfrac%7B-2-2%5Csqrt%7B29401%7D%20%7D%7B245%7D%20%20x2%3D%5Cfrac%7B-2%2B2%5Csqrt%7B29401%7D%20%7D%7B245%7D)
Answer:
a=1/2
Step-by-step explanation:
first we need to isolate a squared. so we add 1/4 to both sides
then you take the square root of a square to get 1/2
to check, 1/2 * 1/2 = 1/4
1/4-1/4 = 0
