Solve 9x^2- 17x- 85 = 0 Give your solutions correct to 3 significant figures.​
dybincka [34]

Answer:

x =\frac{17}{18} +\frac{1}{18} \sqrt{3349} OR x =\frac{17}{18} +\frac{-1}{18} \sqrt{3349}

Step-by-step explanation:

9x2−17x−85=0

For this equation: a=9, b=-17, c=-85

9x2+−17x+−85=0

Step 1: Use quadratic formula with a=9, b=-17, c=-85.

x =\frac{-b + \sqrt{b^{2}-4ac } }{2a}

x  =\frac{-(-17)+\sqrt{(-17)^{2} -4(9)(-85)} }{2(9)}

x =\frac{17}{18} +\frac{-1}{18} \sqrt{3349}
